So is el8 truly incompatible with tcpwrap?  Or is it just too much 
effort to continue suport for every feature that was ever in the system?

If the former, might it be reasonable for a user to change the 8's in 
the code below to 9's?

RPM macros can be quite tricky sometimes.

"The TCP Wrappers package has been deprecated in RHEL 7 and therefore it
will not be available in RHEL 8 or later RHEL releases".

No, because there is no tcp_wrappers/tcp_wrappers-devel package in RHEL8
anymore.

For reasons and alternatives, see:

I should note that if there is enough demand for it I can look into 
building tcp_wrappers myself and supporting it for el8 in ghettoforge 
(as well as compiling dovecot against it).

I think you may be misunderstanding the boolean logic there, the code 
works as intended.
