Most people would consider that fake balance. Having it be stupidly OP and rare don’t really balance out.
It does have other issues, like the lack of storage and need to power it that balance it in a more logical manner.
The storage thing CAN be annoying, crippling if not worked around, but a missing helmet detracts from the REAL reason you wear power armor (not getting your ass kicked), whereas the hauling frame simply makes anything not involving being a walking tank easier.
