Yes. This presumably means some sort of evaluator hook to execute some
code between each toplevel form, or wrap each top-level form in a
condition-case -- reader macros would I think handle it, but elisp
doesn't have those.

Can't you do that trivially by loading .emacs into a temporary buffer in
default.el, then byte-compiling it and throwing the results away?
(In default.el because that way it picks up changes to the byte-compiler
configuration that you may have made in .emacs.)
Downsides: loads the byte-compiler even in sessions that don't need it,
and notably inefficient.
