I have acquired a mid 2012 MacBook Air (MD231LL/A) and I'm kind of interested in moving to big sur, but I'm wondering if it's worth the trouble since I would have to use micropatcher. I'm not that familiar with the changes from catalina to big sur.
Monterrey will be released in the fall and soon after a patch for v15 so wait for that one if haven't migrated to big sur yet
