The problem is with ‘discarding generated deltarpm data’ every day;
please see earlier discussions where Kevin Fenzi et al. explains the
**implementation/policy** issues, for instance at [1].

Deltarpm, if implemented to meet its original purpose, will be very
useful to a lot of people. It might even be useful to all Fedora users
in general as it should reduce network transfer overall. Deltarpm did
reduce a lot of update download size for many years since 2007; it
would be fantastic to fix the implementation shortcomings and maybe
make it useful in other use cases (Edge/IoT) and prepare it for a
better future?
