No, it is a matter of definition, not excuse. M mode means manual exposure based on an external meter reading or the internal meter using the viewfinder EV scale or some other approach (elg. Lunny 11 for moon shots). True manual is also extremely helpful for balancing flash, say for HSS or with on-camera controllers, say for Godox multiple flash setups.
FWIW, I do a large amount of my shooting in M mode, including all of my posts to Flickr in the last 18 months.
