okay

Suppose WT plays Bg5 doing that. If BL then plays h6, and g5 prn, then he incurrs little consequence for doing it, if he is not o-o there yet. (Indeed if WT is o-o and BL is not or is o-o-o, then WT may have actually helped to initiate a pawn storm vs his own K-side by playing Bg5 early.) Whereas if BL IS o-o there then he has weakened his Kings field if he plays h6 aor g5. AND created targets there.
More consequential.
Granted it's a generality and there are other ways of breaking or neutralizing a pin.
And there are cases where it is fine to make such a pin without ...o-o , EG French Defense it can be made so as to get Be7 by BL so that WT e5 push can be made to trade-off the dark Bishops ... of which BL had the slightly better of the two. Just one example.
I agree with you tho, i_play_slowly , that it is valuable to question the axioms of play. After knowing axioms, then Discovering the Exceptions to those axioms that others play by, is part of what elevates a player to mastery imo. (I mentioned sometime back 2 reasons for decisive games. A-execution and B-extra knowlege).

[BTW , In relation to the topic of weakening pawn moves... There is another generality that says Do Not move Pawns on the side where you are under attack. Once you do so, you have created a weakness that Can be exploited if you assume indefinate material and time resources to the opponent.
So the strategic justifications for doing so would be (a) to slow opp's attack there (if yours is raging at some other area:) or (b) to seal the pawn structure there. Otherwise such things can (and should) come to haunt you. ]

Thanks!

A lesson in attacking play — A pawn sacrifice can be incredibly effective if executed properly. As attacking is our theme, that's the perfect excuse to feature a game by one of our favourite chess players, David Bronstein. Bronstein was a true romantic, valuing artistry above results, always prepared to have a hack at his opponent's king. This chess game is taken from our 2009 Book of the Year, The Sorcerer's Apprentice by David Bronstein & Tom Fürstenberg. We could have selected any one of dozens of ingenious attacks, but this one has a strong similarity to the manoeuvre in last week's game – though played 50 years earlier. Bronstein has sacrificed a mere pawn to activate his pieces and expose the enemy king. Crucially, ...
