I see a HUGE headache is asking the user to deal with "changing paths"
just so a few users can have two java implementations installed. Or even
worse asking some sort of software to 'automagically' switch such
declarations. there is nothing but grief in going that route with little
to gain except for those highly specific usages of a untypical and quite
unusual user such as yourself.

i.e. There is nothing whatsoever K.I.S.S. in what you are asking for. And
ArchLinux is *very* SPECIFICALLY a K.I.S.S. style distribution.

however all is not lost for you since there *IS* both abs AND a way to
track specialized PKGBUILDs on specific and particular machines. A user
such as yourself CAN (!) choose to do the things YOU desire without asking
Arch to accommodate what you ask for. i.e. You can do this for yourself
quite easily using the Arch-way once you determine EXACTLY how to
accomplish your configuration. I would suggest you read up on customizing
PKGBUILDs so you can facilitate YOUR specific needs.

Very best regards;
