Maybe they would not play h7-h5 but that does not mean it is bad. Just a positional choice it seems to me. Best eight moves for Stockfish in Multi PV:

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

8...h5 is one of the top four candidates up to d=29, when it starts dropping lower and lower on the list
