My rankings:

BYPASS(PRE), BYPASS(ID):  Never!  These will create an invalid configuration,
one which the vendor is unlikely to have tested.

BYPASS(HOLDERR(id,...)):  Cautiously; after verifying that your system does
not meet the conditions for the problem and consulting with the vendor.
Mention only specific reason IDs in the list.

BYPASS(HOLDSYS): Read and follow the instructions in the ++HOLD text.
Hmmm...  ++HOLD SYSTEM is allowed in SMPHOLD.  Should the instructions
then appear as a COMMENT()?

I don't see how a MODID error can occur unless the vendor has structured
the maintenance stream incorrectly (it could happen).  More probably, it's
consequential damage fom an imprudent (previous) BYPASS(PRE).

Decades ago, I took a class (presented by amdahl) which explained much
of this.  Of course, it targeted customers' concerns rather than vendors'.
