I think I can manage my employer's RPKI data, and I'm not on the
tech/admin/etc handles...
I think I can also ask the person(s) who are to do it and they may have no
idea what I'm asking beyond: "click these 5 things, type that thing,
thanks!"

probably, but ... eventually if your internet gets very small you'll look
at why.

perhaps this is really my point: "I have no confidence that ARIN doing this
(or anyone else except an upstream network/peer) is going to effect change"

I'm glad you enjoyed it... you found the easter-egg!
Generally speaking though (and trying to be constructive) people who use
BGP to manage reachability to their network resources really should monitor
what their resources look like externally... and folk do offer services
which do these things.

"As seen on TV .... bgp monitoring for you!" :)

yea... it's probably as optimistic as your hope that irr data will get
better? :)
I think as more things depend on reachability the state will improve... or
that's my hope, yes.
