Yes, that's problematic - I've stumbled about this problem, too.
If I've tested a package really good before deploying - including
removal - all is fine. But if there is a problem, I have to rise the
revision number, without really using an upgrade cmd (first run of
wpkg.js), then I have the newer package in wpkg.xml with the right
remove cmd(s), and can remove the package (second run).
Perhaps we should only make sure that - before removal is really
done - wpkg checks the revision of this package on the server, and
if it is higher, uses this for removal. Don't know if this works
in all situations, but could save us from the second run.
