I think even at 10 it would useful.

At 20 I would doubt this would show up for any non-cloud user. (but maybe that's
what we are going for?)

My understanding from previous comments was even when the list is long enough to
scroll, it's faster to scroll than type the sink name.  So from my perspective
we are effectively deemphasizing filtering and focusing more on search.

I don't feel strongly about what we make this number though.
