And the opposite approach can't work because the AV scanner + the index
scanner
need the HSM to do its work before they can scan.

I guess the only way it could work is to have levels:
e.g.
HSM agent is Level 1
AV scanner is Level 2
Index scanner is Level 3

When you register at Level N, you are excluded from all blocking/scanning
at Levels >= N,
but your ops are still passed to Level < N.

An example is a little hard to craft because HSM and indexing catch
different operations. :-)
