IIRC, it's a manual process still, so it's not really problematic but it
won't scale well if it becomes a very common occurrence. For now though,
as long as you have the original developer's blessing to use the package
name, you should be good to go ahead. We will hopefully have a more
scalable solution in place before it becomes a burden on us.

Good news, that's already there! In each appname section in your "apps:"
definitions you can add a property names "aliases" that takes a yaml
list of names you want to use. For example:
name: snapname
apps:
appname:
command: foo
aliases: [bar]
By default this will give you /snap/bin/snapname.appname
But then if you run the command: "snap alias mysnap bar" you will get
/snap/bin/bar which you can invoke with just "bar" from the commandline.
Instead of "bar" you can use "appname" or anything else you want to make
an alias for that app.
This still requires a manual step after installing your snap to enable
the alias, but we're working out a process to allow it to be
auto-enabled, which I'm sure will be announced on this list once it's
available.
