I agree.
It will be interesting to see how Rashid Shaheed fits into the WR/KR equation, if he fits in at all. His performance may free up Harty to play more WR. But that still leaves the concern about Harty's size and fragility, although WR may be easier on his frame than KR.
I haven't seen Rashid Shaheed play (not even highlights yet - working my way through some of the UDFAs) so I don't yet know what he will bring to the table. I suspect, though, that Harty's role remains much the same and Rashid Shaheed makes the PS if anything. But we'll see.
