I think these are the right decisions. People who think you should leave early access often think that you will give up working on the game and leave people stranded. Once they get over this idea and see that you have chosen the best path to ensure future development, they normally see sense.
I agree quality of life would be a big help for alpha version. Having to send a single unit out to scout is a time sink while you have other things to do. Also alittle more descriptive text on what to expect for a action or building object. (Like knowing eyes will block paths. Or that picking up limbs have no purpose. Or how to use the whipping posts.) Maybe add patrolling paths.
