I would recommend creating a Bugzilla issue for this under the 'Ports &
Packages' Product, "Ports Framework" Component. It will be automatically
assigned to portmgr@ who can make a call on this proposal.

I'd also suggest commenting the entry (in your patch) so that its clear
why its being done. Something like:

# Use tgz (over xz) here for better installation performance

Nice work!
