Hmm - "blindly track the FHS committee's arbitrary ideas" - that is
a strange way to phrase following a standard.

As far as having more then one version of an application installed
at a time, I can just picture the problems that would cause most
users. It can be done with RPM, but you have to know what you are
doing. It should not be something a package manager like yum should
do. I could see having a plugin to yum that would allow it.
Relocatable packages, and using the blindly --prefix or --relocate
options of rpm. Then manage the applications with alternatives. But
it is not something i would be willing to implement. If you want
that option, you are probably going to have to implement it
yourself, or pay someone to do it for you. But at least you have
that option.

You can ignore the package manager all together, and install one
version in the /usr/local or /opt tree after compiling it yourself.
You will have to give the full path in menu entries, but you will
want to build custom menu items for each version so you know what
version you are running. You could also build an RPM for each
version, but customize the .spec file so it ends up where you want.
For some packages, it is as simple as changing the Prefix value.
