Why? You can easily guess from looking in the config files for TeX and
/usr. The thing which is NOT obvious is that you have to run texhash
afterwards (IIRC the default is set up to require this for /usr/local;
it shouldn't).

Why bother removing it? The casual user will probably loose a total max.
of 20-30 inodes - not many. And removing it is rather silly. /usr/local
is for local sysadmins - they can remove the unused directories themselves.
In fact, instead of creating the directories, we could just put hints in
/usr/doc (but I don't think that's good, because many people dont RTFM).

In fact, I think I just described current policy.
