Here's a FEN of the famous position from the Spassky-Fischer world championship match where Fischer weirdly played Bxh2 on move 29 and Spassky went on to win the game:

5k2/pp4pp/4pp2/1P6/8/P2KP3/5PPb/2B5 w - - 0 30

My father-in-law told me he watched that game live when he was a kid, and he just gasped when Fischer played Bxh2. (This is before engines or eval bars). Spassky did well to convert, but this is more about Fischer's mistake than Spassky.

This is the kind of blunder that you'd expect from a strong club player, not from Bobby Fischer. Although I understand that Fischer was brilliant but inconsistent, and to be fair, the last chess championship matches had a share of blunders.

It's almost a certainty Fischer didn't just "not notice" the bishop would be trapped, he just miscalculated further down the line (in fact if you plug it into an engine, it shows an equal evaluation)

It's one of the single biggest misconceptions ever, it gets repeated endlessly

Why replace PGN, which any decent chess player can simply read and follow (1 e4 e5, 2 Nf3 Nf6…), or if needed play out on a chessboard, with such a huge, unparseable monstrosity?

PGN [1] already supports all the features of BGN. The only complaint of not having long algebraic notation can simply be added as a comment, maintaining the simple readability of PGN. And then it works with the extensive ecosystem of existing tools.
