To clarify, your last paragraph:
today ARIN has an HSM, for parts of the work, but requires that the user
(me, mike, jared) hold our
private key(s) used to sign objects locally. this means that ARIN never
sees the private key material.
a private key would be required to be visible/accessible to ARIN's
system(s) in order to auto-update
a ROA(s) in such a new system.
Further, the future system (that will enable auto-update of ROA) will
need access to the private key
material. This means that POSSIBLY ARIN or a bad-actor may be able to use
that private key material
for bad deeds. (note I'm not saying ARIN is a bad actor, nor that they
want to do bad things)
So folks that need/want to be more assured that their private key
material is 'safe' will need to move
off the ARIN Hosted deployment prior to the new system coming alive.
Maybe that's all super clear to everyone else, but :) sometimes more words
are more better/clear.
