Part of the X (née) roadmap? Off-handed reply? Simple attempt to get a rise out of people? Time will tell. The one thing we can say for sure is that X’s owner responded to a post on the platform today foreshadowing the potential removal of the block feature.

“Block is going to be deleted as a ‘feature’, except for DMs,” Elon Musk wrote. “Makes no sense.” The post was a response to a Tesla fan account who asked whether there was any reason to use block instead of mute.
