Looks like the Paiwan language also use lowercases.

While the French word for the French language is "français", that word is still capitalized in title case. So we would only want to change to a lowercase "français" if the idea were to shift away from title-casing in general. Personally I'd actually prefer the look of things with all sentence-case endonyms, but that's a bigger discussion, and at least last time this was discussed (see description) there was consensus for the title-case approach.

Should French be displayed as français instead? As a speaker of a language whose script lacks capitalization system, I'd say seeing text in lists in sentence case feels weird to me.

Just commenting to say I agree this is not the correct behavior. There's a semantic question here: Is this a list of endonyms rendered in their title-case form, or is this a list of loanwords rendered in the interface language' title-case form? Most of the way the language list works suggests the former. For instance, otherwise we would not be using non-Latin-script names in English, in which most style guides would call for using a romanization. Further, if the goal were to just follow the norms of the interface language, it would make more sense to use exonyms entirely. To me it seems like the goal is that each entry should represent how that language's name would appear in title-case in that language. In the case of Toki Pona, that is "toki pona".

It's been 5 years since the last update and there were a number of changes to the wiki stack. Is this task still relevant?

The above examples are fixed. This is probably thanks to the 8 Oct rollout of the unified mobile router to en.wikipedia.org (T214998).
