It all depends on the usage, I suppose.

To see someone use SMF's and "pretend" to play over them (yes, I've seen people do this) at a gig, a paying one at that, sure wouldn't do much for arranger player credibility if that person's ruse was discovered.

Maybe we'll see more Chord Sequencers on other arrangers now that Korg has initiated it's implementation, although I don't know if I would get a Korg PA3X strictly because it has one. So far, the rest of the instrument is not as impressive as it was hoped to be, at least in my opinion.

The Tyros4 does it for me...it has the sound I like.
