I think it would be good to have a file with the FOL theorems isolated and frozen. By "frozen" I mean that the list of axioms, theorems, demonstrations, symbols and names used would never be changed again. This file would contain only the theorems actually used by the users and could be used as a basis for other studies different from FOL + ZFC. I think I should write FOL + equality to be exact. There was at least one precedent for this. Knuth had found it necessary to freeze the sgb-words file of the 5757 five-letter words of the English language.
