from the bigger picture point of view, buggy rpki implementations are 
irritating but implementation problems like this are not sufficient 
reason for the ietf to create workarounds, particularly when those 
workarounds require new code on router stacks, i.e. have a substantial 
material cost and require debugging.  As an aside, router vendors have 
shown historically that they don't much like supporting cli glue for 
extended communities, so it's difficult to see how they'd write code for 
this.

The ov-clarify draft will probably help deployment in the longer term, 
as it creates a tickbox which will end up on RFPs and compliance testing 
suites.
