It is even safe. INRA, then the major private breeders today, select "hard wheat", the interest of which for baking is measured by the ability to make "bubbles".
There is a device that measures this in a standardized way: it's called the "alveographic test" and here is one of the machine models:

These strong wheats are wheat rich in protein, especially gluten ... We are now looking for wheats ranging from 12 to 14% (I am talking about proteins, not just gluten, but there is a correlation), due to the industrialization of bakeries (pre-baked and frozen breads, then simply "finished" in terminals - a not insignificant part of bread in supermarkets and even among bakers who do not always brag about it; freezing "stresses "bubbles; hence the race for strong wheat more and more" strong "in protein, therefore gluten).

Besides, there are wheats whose destination is animal feed, where we boost the yield even more (and for proteins, we will put soy).
