I somewhat work in that space and the answer from me personally is no. There are a couple of reasons behind that decision for that which might help you. 1. This isn't something I need to constantly check, the standards don't change that often and when they do, there is a lot of noise on all industry blogs about the fact. 2. I can see if the markup on my pages will work by just using the provided tools from most of the major social networks such as Facebook. As a worst case scenario I could just post something myself to see how my pages looked. It just isn't worth the kind of money that you are talking about for me to consider doing something like this. In reality the process of signing up and onboarding me is probably roughly comparable to the work it would take me to just test it myself in my mind.
