If you're hosting a server and don't want to run angelscript, you can disable /plusonly and/or /latestversiononly. Doing that won't evaluate scripts for compile errors... it could be changed to do so, I guess, but I don't see how that would benefit anyone. Also the levels may look pretty obviously messed up with pieces of them not loaded properly. The best way to play without angelscript is to disable all mutators and play levels that don't have scripts in the first place.

If -minimize "randomly breaks," that's a good thing to know about. How consistent is it for you--can you do the same thing twice, and one time -minimize breaks and one time it doesn't?
