I'm working on the assumption that some operators do this out of
operational necessity, not stupidity or "because they can"
Like all assumptions, it is probably flawed.

I've no problem with using PIv6 or indeed separate /32 PAv6 for such 
purposes either, provided the RIR policies allow for such use. This 
may well be the best compromise.

I've seen more deaggregated announcements lately, often connected to 
some kind of business continuity / disaster recovery service. 
I don't like it either but it suggests there is a genuine need that
policy doesn't recognize right now.

I don't like that argument. IMO it plays into the hands of the ITU and
certain large operators where "termination fees" "per-ASN-billing" and 
"pay to play" are certainly on the wish list. 
I can't see a solution either though. In the short term, allowing the
use of PIv6 for this purpose might help keeping it under control.
