I grasp why ISVs care, but also grasp that everybody has different
needs. I, for one, have started deploying RHEL AS 4 and I'm not using
Oracle or anything specifically requiring RHEL. Why? 7 years of
security patches for $50/server/year (academic pricing). I don't really
need to get into the extreme details of why RHEL over distribution X,
but trust me that it makes sense for our situation for such a relatively
low price. Like many other people running servers I don't have the
luxury of being able to take systems down for an OS upgrade at any old
time.

Checking one of my RHEL boxes the VSZ of rhnsd is 5 megabytes, but the
RSS is 532k. I'd agree that it's a blip for me and really necessary
with RHEL if you want to stay secure/stable. And yes, you can go
without it. In fact I run a rather minimal install and turn off many
services that RHEL enables by default.
I have seen userland Linux in general becoming far too bloated without
adding any real new features. The newest libraries are sacrificing
memory/storage for speed. Even very simple things like /usr/bin/yes
have increased nearly 50% since RHEL 8.0. Don't get me started on how
little disk space you could install earlier versions on.
