>for commit, you can't use it with distfiles anyway

Not sure what you mean, as I am quite sure I have been able to change a single line for any ref (branch, commit, or tag) versus having to edit three different occurrences to `v$version` without the _ref variable (as shown below). Are you saying that the distfiles will be wrong for the version defined? If so, I do acknowledge that, but I have had no trouble running clean, then re-genning the checksum in those cases.

Regardless, I have reverted the change for now so as not to introduce inconsistencies or bad samples into the ports tree.
