Further downsides:
Cannot wear a holster (Why the hell can’t I strap a holster to my power armor?!)
Cannot wear a Survivor Utility Belt (come on, if I can craft gear that fits mutated anatomy, why can I not let the belt out a bit so it can fit around the fat power armored waist?)
Doesn’t even carry its own weight when activated (boo hiss).
The comparatively superlative armor is not worth it.
