You're probably right that the CPU doesn't "mandate" subroutine
linkage conventions. You're free to ignore that tempting stack, those
automatically-turned register windows, and whatever other doodads the
CPU provides for your convenience. If you feel like it, you can write
all the arguments to a disk file and have the subroutine read them
back again.

If you plan to write everything yourself, and to make no use of
tools or components developed in the outside world, this is viable.
But if you want to leverage independent work, you must give thought to
doing things in a way that will ease, or at least not impede, the
integration of the parts.
Real-world example: In a former life I worked for the late, great
Sun Microsystems. One continuing and exasperating problem was getting
good device drivers for desirable gadgets dreamed up by third parties.
Company X has a super-duper-speed fibre channel adapter, Company Y has
a video card that is all the rage, and so on. The first thing the
companies do is provide device drivers for a couple flavors of Windows,
then maybe Linux -- but because Solaris had its own device driver
framework, we often wound up with no driver, or paid Companies X,Y,Z
for slapdash inferior drivers ... because we were "better."
Arthur Clarke wrote a story called "Superiority." Read it, if
you can find it somewhere.
