Definitely, it’s a great idea!
The ‘wrap-containerized’ procedure above wouldn’t be hard to write
((guix scripts pack) has something similar). It could use a trick as in
<https://lists.gnu.org/archive/html/help-guix/2018-01/msg00118.html> to
automatically determine some of the default file system mappings.
The next step I think would be to make a package transformation option
for that, so one could say:
guix install eolie --contained=eolie
or similar.
