The most recent breakage was in r36139, changing it from wikitext to plaintext with wikitext preprocessing, apparently in order to support {{PLURAL}}.... which shouldn't even be necessary at all; it should work fine with $wgOut->addWikiMsg as is! :)
The request to support {{PLURAL}} comes from Betawiki for the possibility of proper localizations. $wgOut->addWikiText does the job now w/o breaking customizations.
At a minimum, one should check what format is really being used by the current code. When considering changing it, doing a quick survey of existing usage is strongly recommended. Wikipedians are notorious for using software facilities in ways we didn't expect! ;)
I missed to check existing usage, my apologies.
In this case, the message doesn't need to change format in order to gain the extra capability (this is already built in to the wikitext display) and the extra parameters used for the {{PLURAL:}} won't have any negative effect on an old customized version in wikitext, so it doesn't need to be renamed as long as the code retains the format.
The message names are unchanged, the new parameter with PLURAL doesn't hurt the existing customizations.
