Only one of my T's has actually had a supervisor because he was early on in the profession. The other two had oodles of experiences so they have other professionals they consult with when needed, but it isn't as if they have a supervisor the have to check in with all the time. That has been no problem. I think that term "supervision" is often the same thing as "consultation" really. It may be more of a semantics issue. The reality is that professionals with years of experience tend to work with others in consultation rather than supervision most of the time, and often they are the ones supervising others with less experience. Personally, so long as my therapist is experienced and is willing to consult with others when needed, that's perfectly acceptable for me.
