Hasn't it be a while since HVD SCSI cards were produced? That being
the case, it is entirely possible that at least the fine details of
card programming have changed since HVD. Newer cards may have
dialectic (?) variations, different sets of required workarounds, etc
etc etc.

I doubt that anyone considers HVD SCSI "evil" - more likely the issue
centers around the ever larger test matrix and the need to
periodically cull things from it. And if it isn't tested, it is not
supported:

Supported, known to work -> warm fuzzies all around
Supported, not known to not work -> an HPite may be in trouble
Supported, known to not work -> an HPite is in trouble
Unsupported, known to work -> lucky today, unlucky tomorrow?
Unsupported, not known to not work -> there but for the grace of Turing
Unsupported, known to not work -> no, it was not deliberate ;-)
