snap-store does not start when the user's home directory is not /home/$USER

[Adam Novak]

When I set my home directory to e.g. /alt/home/$USER, I cannot open `snap-store`, the new default package manager for 20.04. When starting it from Gnome, I just get nothing. When starting it from the command line, I get:

$ snap-store
Sorry, home directories outside of /home are not currently supported.
See https://forum.snapcraft.io/t/11209 for details.

How is 20.04 going to deal with home directories outside of /home if critical parts of the system (such as the package manager) are now Snaps? Is that configuration just not allowed anymore?

Is the upgrade smart enough to see if some users on the system can't run Snaps and not transition the old Software Center to the Snap Store in those cases?

I'm not quite sure how to mark this on Launchpad as a general 20.04 system integration problem, rather than really quite being snap-store's fault/responsibility.
