- Is there a simpler way to copy the MediaWiki namespace between
projects, or is it being worked on?
I believe you can use maintenance\dumpMessages.php and rebuildMessages.php. Of course, that requires shell access to the machines where the wiki runs. (But you can get the contents of the Wikipedia's MediaWiki: namespace from a database dump.)
- Is there a simpler way to update language files, or is it being worked on?
Simpler than what? There are some problems with accepting updated LanguageXx.php files into MediaWiki distribution, but there have been some progress recently (check archive). If you mean "simpler than writing/modifying PHP code", than the answer is no, AFAIK.
