Sshhhhhh! You're spoiling it!
For sure, the cynical side of me sees this as a marketing opportunity. If you create lots of subcategories, people need to buy more bikes, right?
Usually, vintage 70s racing frames can handle a 32. There are some exceptions. Pretty much all of the classic 70s and 80s touring frames can as well. No problems for me riding gravel on these types of bikes.
I'd reckon I've put more gravel miles on my old 70s Masi than most official gravel bike riders have put on their gravel bikes.
