I don't think we should have a different data access experience (PWD vs
SNAP_DATA) between services and binaries. This brings some inconsistency
and creates confusion IMHO.

However, I kind of agree now that this is implemented to rather get
SNAP_USER_DATA for commands (as the commands are running as an user) and
SNAP_DATA for services (which are running as root), unless we let them
running as an user.

Does this make sense to everyone?
