On lor.sh we're using patches for tweaks like post length increase, color scheme change or early editing enabled. Because Mastodon isn't about customisation. So most likely it'll be easier to patch language files than waiting for the feature.
P.S. I didn't really check if the option is present because I'm on the phone right now, but I'm not too optimistic about finding it.
@skobkin I used a CSS trick in the custom CSS field, but itβll break when the DOM changes in the next release, Iβm sure.
