I find your rationale and decisions to be wise.  I really did mean
baiting.  And in particular, I really like avoiding the network in a
tool that isn't explicitly about using the network.

Perhaps Ottavio can write a tool to audit pkgsrc for
fetchable-from-MASTER_SITES distfiles.  (Really; I dimly remember doing
a make fetch run on wip to cache things and look for issues about 10
years ago.)
