There are really only 2 pieces you ever promote to: a queen or a knight. If it's a knight promotion it's because of a mating situation where it's quite clear why it should be under-promoted to a knight, so there really shouldn't be a need to display it in the annotation. Otherwise it'll pretty well always be a queen.

At #2 there are some rare instances in which it would be better to promote to a rook rather than a queen. Here is an extreme example where promoting to a queen is bad but to a rook will give you the quickest win

True, there are some very rare stalemate promotions.
Maybe the notation should indeed read properly something like h8=Q or h8=N etc. Is this something to do with Stockfish itself or is this on the lichess end?

Underpromoting to rook wins. Promoting to queen leads to a stalemate.

Underpromoting to a bishop can induce a stalemate.
Sometimes a bishop underpromotion ( http://en.lichess.org/7kB4aVAI/black#106 ) can win faster than a knight underpromotion
( http://en.lichess.org/l2vuGFmP/black#108 ). Rook/queen promotions would lead to stalemate. Marching the king from the other side of the board would be ... a hassle. Then again, it's possible to win just as quickly in this scenario without promoting the pawn ( http://en.lichess.org/VSbJvEXT/black#106 ). Of course, these are just post-analyses of the training exercise ("puzzle after story 33577"). The attempt itself was awkwardly longer ( http://en.lichess.org/WbAGRxfm/black#122 ).
