I think the concern was more about the effect of the replacement than how to implement it.  For example, the test changes in this patch provide evidence the effect on OpenMP seems fine.  There might also be external use cases, so reviewers who are more familiar with specific pragmas (like Alexey for OpenMP) might have more info on those.

Sure.  I discussed the possibility of adjusting all pragmas (to see the effect) before pushing any changes for exactly that reason: a reviewer previously suggested waiting due to his concerns over creating inconsistencies among pragmas, some of which might have use cases OpenMP doesn't, if we pushed the OpenMP changes in this patch immediately.  I think the majority now feel it's fine to go ahead, but hopefully that isn't just because I didn't explain the previous concerns clearly.  Anyway, I'll wait a few days to see if there are more comments.
