When it comes to Python in a role of system initialization
there are some very simple things one can do that would

go through that step. One could ship the distribution with those
modules pre-compiled and only edits from that point out would be
compiled on their first run.
Hmmm... Now, that's a problem! During the early part of the boot
process the root filesystem is read-only until it's been fsck'ed.
There's no safe place to put the compiled modules.
Not to mention that moving 10 MB of Python from /usr/bin and /usr/lib
to /bin and /lib would increase the size of the root filesystem by
10%-20% on embedded systems -- where the size of things that must be
in flash is a critical resource.
