Just wanna play devil's advocate.
I feel as though static stretching could be useful in pursuit of hypertrophy.
In the grand scheme of things, it takes a challenging load/resistance, along with proper stimulation to induce growth.
With that said, tightness causes muscle inhibition. Namely in the stabilizers. Not only does muscle inhibition increase the risk of injury, but it also reduces the amount of output via golgi tendons/muscle spindles.
An example we'd all be kind of familiar with would be a KB press. Someone with a lack of mobility in the shoulders (usually due to inhibition, incorrect firing patterns, flexibility) would be limited in the amount of workload the shoulder can handle. Now this is interchangeable with any exercise really. Someone who can only quarter squat because of hip tightness. Or maybe they can't go too deep because the back rounds due to hammie tightness. etc etc.
I understand OP is asking if stretching directly induces growth... but if you think about it, nothing you do 'directly' induces anything. It's always a combination of work, eat, sleep, and the micro managing in between that makes the difference.
Just a thought.
