[20:47:52] <Krinkle>	 If someone here has experience with language variants and LanguageConverter in relation to interface messages in MW, could use a second pair of eyes on https://gerrit.wikimedia.org/r/c/mediawiki/core/+/737449.
[20:48:34] <Krinkle>	 It looks right, but its a surprising amount of boilerplate that I'm wondering maybe is already handled somewhere or maybe violates some unwritten convention for not doing this for content language messages.
[20:58:01] <bawolff>	 Not sure if this is still applicable, but it used to be that converting something with language converter had stateful side effects, which if it applies here might be confusing (because the stateful side effects would only happen on the non-cache path)
[20:58:06] <bawolff>	 not sure if that applies here
