Yep. In fact, the first releases of MAME had 0.01 increments. Not sure when they went to finer steps, but it is pretty much a given that they'll do it again when the current revision gets too close to 1.

Version numbers don't work like that :)

MAME just has a permanent "0" major version, and the minor version continues to be bumped up forever. It's not a decimal number, so "close to 1" doesn't really make any sense.

Ehhhh… while there’s no particular decimal cut off, “closer to 1” is always going to be a higher minor version.

It’s not incorrect as such
