I would like to propose the following patch to bsd.pkg.mk. It prevents dist
files not existing locally (any more) from being fetched when the package
in question is resumed building, installing or packaging and has already
completed the patch stage.
After this stage (please correct me if I am wrong here since that's
critical to my proposed solution!) any dist files will no longer be used,
so fetching them serves no purpose and wastes resources.
This situation can occur if one does a bmake install or package for an
already (at least partly) built package whose previously-fetched dist files
have been removed in the mean time (e.g. to save disk space).

I have previously addressed that issue in PR#25432.
I would be happy to hear your comments.

Thanks,
