The FAA has finally formalized extensions for Part 61 and others...
Not to my knowledge. AFAIK, and as far as AOPA has announced, the only step the FAA has taken is to forego enforcement of medical expiration dates through June 30. Nothing on 61.56 flight reviews, annual 61.58 PIC checks, 61.57 recent experience, etc. Have you seen something to the contrary? If so, please share it. Here's where you can get the latest official information from the FAA on this subject:
I'm sure you're right... I was skimming the news for Part 107, saw "extension", and turned the medical extensions into something bigger.
Again, there is no "extension" of the medical certificate. The FAA said only they won't enforce that rule for flights made between April 1 and June 30 as long as your medical was valid on March 31. And, as the FAA and AOPA both said, there may be serious financial risks if your insurance policy requires a current medical.
