I had both -devel packages installed previously and they apparently 
started to conflict very recently.
Normally I have -devel packages either because they were pulled in as 
dependencies, or because I was compiling something else that required 
their .h files or something like that.
I don't remember which one was the case here, but please note that 1040 
packages require openssl-devel and 265 packages require 
compat-openssl10-devel as reported by "dnf repoquery --whatrequires 
xxxxxx". I believe that most of those dependencies are specified as 'one 
or another' which is why this situation can be resolved by allowing 
erase of openssl-devel.
This is actually suspicious---I think it DOES matter which openssl 
version we're compiling/linking against, and applications have to be 
ported, if ever so slightly, from 1.0 to 1.1... but I don't really know 
the situation here.
