It is impossible to predict whether they need not be changed for any
current or future processor or toolchain. If you really want something
with a fixed layout, then a new concept has to be introduced in which
you can precisely specify this layout in a way that is endian-agnostic
(rather than just declaring types and hoping that the compiler will
forever lay them out the way you need them).
Bitpacked arrays and records are not intended nor suited for that
purpose.
