Conventions/policy regarding packages in pkgsrc-wip that use wip/mk/git-package.mk

[Aleksej Lebedev <root%zta.lk@localhost>]

Hello, everyone!

I just noticed many packages in wip that end on -git.
They all use wip/mk/git-package.mk which seems to allow fetching sources 
directly from git.

This seems great for development, but I'm not sure if it gives any 
advantage for "stable" packages.
What usually happens when these packages get imported to the main pkgsrc 
repo?

Is it OK to have both versions of a package, one that uses 
git-package.mk and one that fetches a tarball?

I happen to submit wip/toxcore (with fixed version 0.1.11) before 
realizing what wip/toxcore-git package is.
