Some people say they're all the same timeline. Others don't. If other shows follow what some showrunners say and "Rule one: The showrunner lies" - for which some do, some don't, some don't say anyhing, others misdirect but get to the same thing in the end... meh. Either which way. there's enough in headcanon for anyone to go either way.
I'll just enjoy any show for its own merits and ideas and haven't returned to the ones that didn't work as well. Most people seem do just that, and plenty dislike TOS and for plenty valid reasons too.
Wake me when they have two barnyard and/or bog animals going at it on screen and saying it's canonical and not a holodeck program being viewed. Everything else has been done, anyway.
