   This error class is pretty JSON specific. So, add JSON in the name. For example:

Review Comment:
   I'm conflicted about this. If something is LEGACY, then shouldn't it only apply to existing use cases.
   Should we really advertise such configs?
   On second thought, I'm not conflicted at all, FWIW I vote to NOT refer to legacy configs.

   ahh, I missed that it is a legacy config. I agree to don't advertise it.
