I fully agree with Norm's demand that all theorems in set.mm (at least in the main body of set.mm!) should be minimized, but I am of the same opinion as @savask that tagging minimized/not minimized theorems as proposed by Norm is not practicable and would make set.mm more clumsy. At least I

I agree that minimization markers "add no value", so in my opinion they should be kept out of set.mm altogether. Maybe we can create a file "minimized_theorems" (something like "discouraged") which will be a list of, well, minimized theorems :-) Contributors won't have to set any tags or

In the past, every year or two we would run "minimize_with" on the entire set.mm. But as set.mm has grown, doing this has become a somewhat large project. The last time was in Feb., which involved people volunteering their CPUs over several weeks as well as my time managing it. BenoƮt
