*ALT theorems in the full job logs (not just the suspicious proof size 
decreases that I posted) are creating unnecessary manual cleanup effort to 
get  things to a point where I can run the final minimization.

To avoid this problem in the future, I am wondering if it would be 
acceptable to make Benoit's suggestion mandatory and to have 'verify 
markup' check for it.

Does anyone see any problem in requiring *OLD and *ALT to have both 
discouragement tags ["(New usage is discouraged.)", "(Proof modification is 
discouraged.)"] always? Is there ever any reason for not having these tags? 
(If in some special case an *ALT could benefit from 'minimize' or a proof 
revision, we can always use '/override' on a custom basis for that purpose.)
