I understand what you mean.
If you want you can drop the megatech, neogeo, & stv XMLs onto the CMP profiler OR use the Add Dat File function and also create 3 empty directories with the same names.
Then jump to rebuilder top 3 options checked and remove matched source files NOT checked.
source: mame roms destination: the empty directory
then you can have those directories ready and be prepared if that change happens to take place.
