wgGrammarForms for cs is quite different from other languages. It uses "sg"s and "pl"s. It looks like these have been already added (Gerrit change #61779) although "sg"s and "pl"s have been used. So can this be marked as resolved? See https://github.com/wikimedia/mediawiki-extensions-WikimediaMessages/blob/master/WikimediaGrammarForms.php#L177
Eh, those forms do work on Wikipedia etc. but they don't do on the translatewiki.net repository. I should have checked both. Marking as invalid.
