I would like to receive an authoritative answer, are there any built-in limitations in the OS
I am afraid that you will not receive any authoritative answer, because any supplier (for example, Sony, Samsung, HTC) can not only add their applications to the system, but also configure any other platform parameters. And there are various androids, such as AOSP, but also, for example, CyanogenMod's. Usually they do not publish such information, so basically it would be just a blind guess.
