Rarest Chess Move

What about KG8#?
I wrote already king mates are rare, so yeah, Kg8# is rare.

sorry if i sound dumb but is it possible to get a disambiguated en passant checkmate? im just curious because ive never seen anyone even talk about it
Disambiguated non-capture en pessant promotion to knight checkmate
impossible, for en passant can only happen on the 5th or 4th rank, and promotion happens on the eighth
