use minor FreeBSD version numbers in package repositories

Dear FreeBSD Community,

First of all, I would like to assure everyone that this is not a
complaint and that I would simply like to offer a useful idea for the
future of FreeBSD. Could we please start using the minor version
numbers in package repositories? This would be conducive to having
stable reproducible jail builds. I know that the canonical answer to
this is "build/copy your own packages tree" but, in the age when
storage is so extremely cheap, do we really need to put everyone
through this torture? Thank you in advance for your consideration.
Please help me to understand what would be necessary to make this
happen or if this is perhaps something that is already on your radar?
Looking forward to hearing from you.

Kind regards,
