IMHO, no.

There are also too many compatibility shims in front of the domain builder,
i.e. all the stuff in tools/libxc/xc_dom_compat_linux.c which IMHO could be
nuked too.

Right. 

Removing the superpages option from the non-Python might cause concern for
some. Adding Konrad since IIRC PV superpages is a thing Oracle implemented
and might still care about.

Also adding Roger since he is reworking the HVM builder to use the PV one,
which for all I know might involve using the superpage option (but probably
not the PV code to set it up).

Also CCing the other tools/libxc maintainers.
