That ship sailed long ago and isn't coming back.

"All the world is your laptop" is pretty much how it is for current
students who become the next developers.  Letting people emulate
their laptop sufficiently well on a cluster will help quite a few
non-CS users.

Even for CS-ish users, home directory servers cannot support
undergrad student numbers at current available funding levels, there
are no central computing labs where people access them, etc.
Students really aren't even exposed to shared home-directory style
filesystems short of data dumping places equivalent to Dropbox.
Installing into the home directory no longer occurs to people who
own the entire file system.
