Hi Adam,

Considering that's one of the key scenarios for which RPF is known to
NOT WORK reliably, I would have to disagree with that statement. Folks
running BGP expect to manipulate routes asymmetrically.

If you had said, "It's a pity that RPF is not on by default over
interfaces for which no routing protocol is configured (connected and
static routes only)" I might have agreed with you.
