Oh, right. As for any controversial thing the discussions on this stuff
goes on and on :) and we all repeating ourselves from time to time as time
goes. I'm sorry though for making a blast from the past.

Yeah, this is controversial. Anyway why UIA mapping is different? Is it on

I guess I would go with the approach to ignore the role in such cases, as
it wasn't present at all. Was there any agreement on this topic (I may be
missing some of past discussions)?
