Yes, FS and BBBJ have been a standard option from MA's for a long time, especially from the independent variety, so it's not a new development. However, what is new is the recent openness of providers to admit to it.
I think the recent challenges to the laws, and their subsequent striking down within the Ontario courts, has made it easier for this openness to begin, at least in Ontario. Until the case is seen by the SCC, it'll still be a little difficult for providers outside of Ontario to be as open about it. Once it's seen by the SCC (and assuming it's successfully struck down), then it applies to the country as a whole!
Personally, for the last several years, I have preferred seeing MA's over SP's, mainly because I find an experience with an MA is more organic, while an experience with an SP seems more business-like. Clients who see SP's seem to come with a list of demands, and they expect it to be all provided if they offer to pay more for it. Clients of MA's aren't necessarily looking for a set of specific services that they want checked off of a list, and often they may not even get everything.
