If there was an accident, do you think they'd just take your word for it and drop it? I doubt it.
Also, where do you find FAA guidance for BFRs?
This is just a personal account, and doesn't by any means prove what the FAA will or won't do, so take it for what it's worth...
Way back when I was getting my airplane add-on, I had an engine failure on a solo cross country. I put it down in a small field and the wings were damaged by some small tress.
I did all the required reports, NTSB stuff, etc.
No one ever checked my logbook for endorsements. No one ever checked my instructor's records. In fact, no one aside from the NTSB ever talked to me, and no one at all talked to my instructor. I guess the FAA picks and choses what they get involved with.
