I don't understand what you want to say here - but for sure on Linux
the distinction between data and programs as described by Phil has a
long tradition, is mandated by the Filesystem Hierarchy Standard and is
usually followed quite strictly.  Not to forget that TeX Live has
inherited from teTeX a build configuration that allows it to be easily
adapted to this separation: binaries end up in /usr/bin, data in
/usr/share/texmf*, variable stuff in /var/lib/texmf.

This is a valid argument.  However I'm not sure whether normal users
actually install different versions in parallel, or whether it's not
equally "normal" to want separate partitions for programs and data.

It seems the installer needs an uninstall option...
