One could easily presume the ARIN region RPKI deployment statistics are lower as a result of the RPA situation (and no doubt that it part of the issue), but as noted earlier, it's unlikely to be the full story since we also have a region (APNIC) where RPKI deployment also rather low that and yet does not have these RPA legal entanglements.
It was suggested earlier that this may be due to a combination of factors (education, promotion) beyond the RPA legal issues that are now being worked - so that will also need to be addressed once the RPA is resolved.
definitely agree. lacnic and ripe have put effort in their respective communities (yay alex!). heck, ripe even resolved the PI and legacy policy issues so everyone can play (speaking of sick arin legal documents). randy
