Sounds good to me from the little I know of it, albeit I do imagine it
could raise issues with some packages that try to use/handle TZ
themselves and no telling what obscure thing this is going to break.

exa[1][2] is one example that sam mentioned, but I imagine there's
more to find.

Personally added to /etc/env.d locally anyway, will see what come of it
for the things I use, not that this covers much at all :)
