I'd say this is already covered by 
<https://www.mediawiki.org/wiki/Localisation#Avoid_message_reuse>: even 
core shouldn't reuse a core message for different uses. The big 
exception is «"{{int:<key>}}"» literal quotation in another message.
For instance, core reused "createaccount" for the top right link, when 
it was the title for a special page. This led to very weird results e.g. 
in Italian.
