Recovery? The only Steel with recovery is Skarmory, which you're better off using Rock Blast on regardless. Nattorei, on the other hand, doesn't have reliable recovery, so that's not really a major change.
Besides, the difference between walled by Steels is huge; that's one of the main differences that puts Staraptor above Swellow, since the former can Close Combat past those, while Swellow is pretty much walled by any Steel, relegating it to a late-game sweeper, while Staraptor can generally come out even if the Steels haven't been eliminated yet.
Thus, it's pretty obvious that being able to hit steels for nice damage is going to let it be more versatile on when it can work.
And y'know, you can always just ignore the responses if you want.
