Sure, one can argue that Migen is for synthesizable code only,
and for the rest we have Python, so that's OK, isn't it?

Well, no. Look at the test bench code versus Migen code and
note that the modeling paradigm is entirely different.
But in practice, today's high-level model that is part
of the verification environment becomes tomorrow's
synthesizable model and vice versa. Very often, this even
happens within the same project.

Refinements may be necessary, but always within the same
modeling paradigm. Having to switch between modeling
paradigms depending on the particular view is unnatural  and
leads no needless modeling effort duplication. The great
advantage of the event-driven paradigm is that it is
general enough to provide a single modeling paradigm
for any type of logic.
