It also breaks if you export /usr/share to systems of different archs
(nobody actualy does that it seems) and will break with multiarch (far
more likely someone will mix archs there).

Depends on the size of the patch. Then again if the patch is small
upstream will probably just include it.
It will just be a matter of waying costs and benefits. How much data is
there? How difficult would it be to convert the data at startup? How
difficult would it be to build a -le and -be data package (on a single
arch)? and so on. There won't be one solution that fits all and I think
there will be packages for each solution presented so far.
