For sourdough and breadmaking, I always find it funny how recipes and tips make out like yeast is almost delicate and hard to keep happy when we know yeast is super tough. It can survive drying, cold/freezing, high pressure, having no food for a long time, up to 50C heat, and more.
It's also easy and cheap to run experiments too like mixing salt directly with the yeast and seeing it doesn't make a noticeable difference to breadmaking, yet the myths persist.
The problem in general is consistency. Bread is very forgiving on flavour profiles so what you're saying works fine within a good threshold. For breweries it's usually not worth it as there are lots of nuances on the mutations of the harvested yeast and their effects into the flavour profile of the final product. There are some exceptions like natural fermented beers or anything related to kveik yeast, but in general people don't reuse yeast past 1-2 brews.
