Review Comment:
You are partially correct. All implicit scans can be RO. But, currently
it's possible to create RW-partition scan. And it has completely different
semantics comparing to RO scans. So, my optimization makes total sense for this
scenario. Until this possibility is removed from code base, I prefer to retain
my optimization in the code.
