bq. Removal of code is not zero-risk, and this is 4.0 GA branch. Much like we 
don't do small improvements on non-trunk branches, my understanding is the same 
logic means we also don't do code removal / cruft cleanup / other refactors on 
non-trunk as well.

I definitely agree with all of that.  However, this is platform-specific code, 
and it could be argued that not removing it when Windows support was deprecated 
is a bug; after all CASSANDRA-16171 took a first pass. Significantly though, 
the genesis of this ticket was the implications of this cruft on security in 
CASSANDRA-14612.

It looks like after the holiday break there's been some branch->CI disconnect.  
I've started runs against these branches, which I think is accurate, but please 
correct me otherwise:

> more there are some source files that can be removed.
