My enthusiasm about this particular version, that I had been looking forward to, waned quickly. I'm about to start the new project after I finish up my previous one, and I'm currently waiting on getting the design document. I'm doing the opposite of procrastinating, I want the project to be done smoothly and in a reasonable timeframe. Having to contend with conflicting information where almost everything I look up will be for 3.x and not applicable to the 4.x series is the antithesis of smoothly.
So it seems now that my choices are to go with Godot 3.x and end up with maintenance trouble in the future and not being able to make use of 4's much improved feature set, go with Godot 4 and have a much rougher development experience, or go with another engine altogether.
