This is exactly what I have suspected.  ups/401 is widely known since it 
features in /etc/services, but it has no users.

In an I-D [1], I explain that I would like to use port name "ups" for UPS 
management over TLS 1.3 which is not available in the current NUT (Network UPS 
Tools) package 2.7.4.  Such a "take-over" is not evident, since for example 
direct transfers of IANA names and numbers are not allowed.  One of the hurdles 
to be overcome is demonstrating that "ups" is not being used.
