Vaguely remembered, mostly forgotten, quickly checked and claims to have cut 2Mb .. and it does indeed reduce the image size on disk. That’s also cut 7000 MCinfo-wotsits so we’re down to just 2500 (why are any left?) and a similar number of DateAndTime/Date/Time, so clearly they are tightly related.

 (Fun aside; inspecting MCVersionInfo allInstances, select one at random, ‘chase pointers’ - and a large list of updates start loading…. adding 13Mb to the image size. Yippee.)
