Sounds very reasonable, I understand the criteria for selecting languages for inclusion, even though I’d really like to see my dearest Icelandic be one of them.
So the next question is: Where precisely is the bottleneck for incorporating more languages?
Is it in the CMS (I doubt it’s due to Weblate itself), is it a memory problem in a VM or a hardware issue?
I have translated several websites through platforms like Weblate; some have no problem with publishing a bunch of languages, while some (like e.g. Tor) are very reluctant in adding more languages. Perhaps we should investigate similar setups and compare the components (e.g. is it Weblate → Git → CMS or straight Weblate → CMS?).
