Yes, but RSTP MIB contains the extension to bridge MIB and should
have my proposition (or another solution of this problem) as a correction
along with dot1dStpPathCostDefault.

Yes, you understood me.

Me too.

As I pointed above, I think, that you are right, and it should be added to
RSTP MIB.

Apropos, what about MSTP MIB?

Thank you for an attention to my remarks,
yours sincerely, Alex
