It is not untenable. All you have to do is make the script take input and save the selections somewhere.

If the chosen destination is /opt/yoursoftware/version

you can easily create an /opt/yoursoftware/latest that is a link to the version installed.

Windows does not have the major advantage here. Sure you can play games with the registry, but *nix has been more flexible for decades. Nobody is suggesting you build an alternative to deb or rpm files, but you don't have to use them at all, and it makes it even simpler for dealing with any ELF compatible UNIX.

you have a tgz file, and then it explodes into a directory. That then has an install.sh and perhaps an uninstall.sh and perhaps an upgrade.sh script inside.
They do the right thing, and create backups, and the version management and voila.

If you run uninstall.sh, it then asks if you want to save your current version. If so, you can easily archive it off, because /opt/yoursoftware/latest points to the one they just installed.

This is the way *nix works.
