In the new messages MediaWiki:Userrestricted-* , there is a series of almost identical messages differing only in line 1 (of 8). Similar situations exist elsewhere.
IMHO, both maintenance, and translations, would gain from splitting such messages, i.e. putting the constant part in an extra message. Of course that should not be done when there might be reasons to assume that, depending on language, localized versions will need to have differing pieces where the English originals have 100% identical texts. In the case mentioned, this is most likely not so.
This is not a real bug, rather a general suggestion to follow. (E.g., I am not asking to alter such messages now, once they exist.) The cause for me to report it here is mainly that I have not found a better way to collectively address those who it may concern.
Thank you.
