Not just versions -- large organizations have quite different setups.
Some want HOME to be a network drive, and hope that any user can
walk up to any PC, log in, and run with their files, but in practice many
applications store things on the C: drive so you end up with messy
login scripts to load the user's settings into the registry.

Not undocumented, just undisciplined because it has a legacy of
monolithic apps that take over the machine.

Users expect to move EPS files around but discover that some files
that can be viewed on system A have font problems in system B.

It will take several more years before the older gs installs are updated.

Certainly the ideal is to encourage 3rd parties to fix problems (in
functionality or licenses) so they play well with TeX Live, but I
suspect the problem will always be with us, so a mechanism to support
private TL binaries could make it easier to ensure TL has the
necessary 3rd party support with reduced risk of conflicts.
Installers can check to see if gs, perl, etc are available, but the
live version isn't so flexible.

Which is reason enough to have a stripped down perl that is adequate
for the scripts used by TL.

You can be sure there are people working hard to come up with even
more horrible licenses such as usage based charging. The problems we
have now will only get worse.
ConTeXt now has a "texmfstart" wrapper that tries to hide the
differences between platforms and TeX systems. Certainly most
Windows users expect to use TeX in some environment such as
WinEDT (and lament the passing of 4allTeX), and seldom, if ever, use
the command line. I suppose the extreme would be to leave the
bin/Win32 directory out of the PATH and insist that users who aren't
comfortable with the command line work in an environment that runs
the programs from buttons and menus.
