Likely just due to gateway status, or an AD that has yet to be "primed" (no image yet seen), etc.
This doesn't really belong in typhos, nor pcdsdevices - perhaps ophyd, I suppose.

But what could be preferable? Raising a different exception that we can catch specially?

(Not really sure there is any better path forward; recording this for discussion / future reference at least)
