2.,3.) The Breton and Nahuatl Wiktionaries have no community yet, but it
would make sense to turn the capitalisation off because Nahuatl is
mostly written decapitalised and also Breton does differ between
capitalised and non capitalised words.
It makes perfect sense to turn off the autocapitalisation while those
Wiktionaries are still small.
Als has 1 (2) active members willing to make the necessary changes
on Br there is no work to do at all, on Nah I myself will do the changes
(which also are very few).
on Sr there is a community which is in favor of the changes (with no
votes against) and willing to do the changes.
Many thanks in advance,
