Tbf, even if we stopped literally right now that doesn’t address what’s already there so even best case scenario would still be a little of column a, a little of column b.

Honestly I think your first point is just a subset of something larger and even more basic - “we’ve always done it this way. Change is scawwy. Different bad. Are you implying I was wrong before?” Etc.

Honestly for Philly cheesesteak your best option might be to marinate some portobello mushrooms in olive oil, vegan worcestershire sauce, a bit of soy sauce, and garlic, then slice very thin and fry for the “steak”. Worcestershire and soy sauce together do an excellent job if you want to add a beefy flavor to something.
