I was asked to weigh in on https://pagure.io/releng/issue/7215
priority. Last time we talked about this we didn't really get anywhere...
... and that ticket hasn't moved, because fixing it isn't trivial.
What we're doing now — as has been the case for several years, already noted
in the previous discussion — has very little end-user value. Also as noted
in that thread (as in the ticket)... that's unfortunate, because it did
bring some real benefits (and could possibly do even more.)
But, I think it's time to move on. We have ostree and various
container-delta approaches. We should focus on those — and give DeltaRPMs a
sad, fond farewell.
