Scripts on here: Same, but different?

Sorry if this has been discussed before, but I need some clarification about scripts of similar appearence but different. Couldn't find something similar, but may have missed it…

So I'm in no way a lingustic (maybe by hobby only), and I'm not symbol reseacher either, but I was adding some North Borneo notes, like this one for instance N#456371 and I was told one of the script was Jawi.

My question is just, isn't Jawi a modified Arabic script? Does that mean I can request eg. Dano/Norwegian, Swedish or Icelandic scripts, since they are modified Latin script, but still different with modified letters and some different letters too?

There are probably other similar cases with scripts having similar appearence, but still different. I know that can give birth to counter arguments about where to put the line then, like isn't Greek just a modified version of Phonecian. 

I still hope my point of my question is still understood, since I'm slightly confused and would just have added Arabic as the script for the note I gave as an example.

Hello,

I have the same doubt as you. Any advice from script experts are welcome.

Here was my reply when adding the Jawi script last November:

Hello,
 

I added the Jawi script.

 

I have a doubt about those scripts that derive from the Arabic script, also including Persian and Urdu. 

We don't differentiate alphabets for Latin script(s), even if some countries use different letters than others; for example, Icelandic uses Þ and Ð, Spanish uses ñ, etc.
I'm not knowledge enough about Arabic scripts to understand whether there is a good reason to have Jawi, Persian and Urdu and not Icelandic, Spanish, etc.

According to Wikipedia, Persian and Urdu are both variations of the Arabic scripts

https://en.wikipedia.org/wiki/Persian_alphabet

https://en.wikipedia.org/wiki/Urdu_alphabet

But for Urdu it's (often) written in a different style than the Arabic/persian written in other countries.

On Omniglot they also treat them as the same overall script, with local variation:

I'll probably more ask what's the argument for seperating the scripts?

My argument would be, if we take the script drop down list with examples (like we have have in the main menu of the searchs thing), and the Jawi, Urdu, Persian and Arabic can't be destinguised (beside the word itself being different), then they (may be) are the same.

Maybe have some native speakers/users of the scripts into account as well? Anyone who wants to give their opinion?

Instead of having Arabic and Persian script, I we could use Perso-Arabic script.

Jawi script is generally seen as its own script, seperated from the Arabic script, and not like Czech and Swedish, which are both considered using the Latin script.

We also have the Pegon script whic his used to write the Javansese, Sundanese, and Madurese languages.

I see your point with the Greek script (alphabet), but Greek is both an alphabet and a language. Cyrillic is derived from Greek, and so it the Latin script. So with this logic we should just scrap the whole “script” idea. 😉

Same as Greek is Armenian, which also both is a script and a language.  

I dare to poke and ask, what's the argument for having Jawi and Pegon for that matter as seperate scripts? I would be able to differantiate, eg. Cherokee Greek and Cyrilic, but not Pegon, Jawi, Arabic and Persian..? 🤔

Aren't they just  Arabic with some extra letters, like Danish, Swedish and Icelandic to Latin?

I know a part of it, is of course being a reader of the scripts or something similar. But let's play with the general idea here 😁
