Comment 14 for bug 339326

Yes, there are. Ugh-y code, untested code path, perf, maybe others.

Whether those outweigh the benefits in the use case of a linux distro is a completely different question. Linux is the only platform we ship on as default, thus the multi-locale use-case is completely different there than on the other OSes. And they can hack stuff to make some problems smaller, or just buy it.

That doesn't mean that we should change our setting here for the builds we ship, as those target a particular locale.
