First, thanks for doing this! It really shows a lot. I'd be really curious as to what's in the remaining 144MB, given that Alpine and BusyBox can get away with a userspace which is 25% of that size.

As Dan points out, we can't necessarily dispose of DNF/Yum during the standard container build (i.e. Dockerfile). However ... could we remove them afterwards?

I'm also wondering if tzdata will be a problem. Some applications, like webservers and database servers, do need the tzdata files, but I suspect don't have it marked as a dependency since they're assumed to "just be there". Would be nice to remove them when not needed, though.
