I don't really agree with all of the nonsense that surrounds this. But,
from the system release notes for version 220:

Those who don't learn about UCSPI are doomed to reinvent it badly, as here.

On that note, I am happy to report my discovery that GNU inetd has
UCSPI-TCP support.

And I am interested to report my discovery that Laurent Bercot and I are
on one side of a design choice with Felix von Leitner and Erwin Hoffman
on the other.

And I am regretful and slightly hesitant to report a security bug in
s6-networking, where it fails (unless I have missed something) to wipe
any existing UCSPI-TCP environment variables that it isn't setting, per
the spec, but merely _merges_ environment changes.
