I like the change, but I think that modifying $table and $uid can be
dangerous, as we call a hook later (clearPageCacheEval and
clearCachePostProc) that gets $table and $uid as input. So if there is a
hook out there that wants to handle something on a cache-clearing on
specific page_language_overlay's, it will no longer work.

So +1 if you modify it not to change $table/$uid anymore, or convince me
that this is not a problem at all. ;)
