After looking at PR 61597, I updated the 2 conditions to:

a PARM_DECL is a local variable and returning its address is wrong,
isn't it?
Right. It can live in either a caller or callee allocated slot.
When I first glanced at the patch my thought was "why is this in the
path isolation pass?" But I see you want to modify the returned value
to be NULL. I'll have to look at why you want to do that, but at least
I understand why it's utilizing the path isolation code.
