As far as I understood, this only works for the user who runs the
command. So if multiple users used "vam install addon", each one would
have to run "vam remove addon".

Ok, then it seems to be harmless. :-)
I am thinking about another case: A package initially consists of one
file. This file is symlinked because some user runs "vam install addon".
Then the package is deleted. So the symlink point to nowhere. A newer
version of this package contains the old file and a new one. This
version is now installed, but no "vam install addon" is run. Then you
have a halfway installed package, because one file is symlinked and the
other is not.
Is something like this possible? Does vim-addon-manager have some
mechanism integrated to check for this? Something like "vam cleanup" or
"vam --all remove addon" would be nice.

Actually I haven't thought about this. Maybe my idea was not that good. ;-)
