Me neither. The design of those apps is 30 years old, I wasn't even
working here when that was done. The stability of the OpenVMS ecosystem
is such that this design never required to be changed.

Totally agree with you there, but it's not me who decides. Basically 
the
applications contain the node name hardcoded in them all over the 
places
and changing that is expected to take months of work. Limited
development workforce, limited deep OpenVMS skills (harder and harder
to find, if we ever quit OpenVMS, this is likely to be the main 
reason),
and always more urgent functional needs...
