Whee!  I have a user!  :-)

Yes, if there is no significant userbase, it will stay in RELENG_7,
but will not be in RELENG_8.

My worry is that since I don't use the GPIB cards anymore, the code
will be (already is) pretty unmaintained, and thus likely to rot

If it transpires people are actually using it, things are different,
but it needs to be users, not just people who thought about playing
with it.

It can do a full bus, you select the different devices using "magic"

Never attribute to malice what can adequately be explained by incompetence.
