IRR contains data - question is can you trust it? RIPE has cleaned up their stuff, sure, but the rest of the IRRs out there haven't. Next question is which IRR once you get past the RIRs? AltDB? There's a few out there. Lots of crap objects and proxy registration, that said there are a lot more things in IRR than ROAs out there. I do agree with you that routing vendors have made this difficult to easily ingest prefix list data for easy import into inbound filters. There have been NANOG presos from last decade showing the performance hit when you try to do this at scale. It is much easier to enable RPKI OV than it is to build a robust IRR filtering system.
