Hmm, maybe in some areas but not others:
On the one hand the whole PUTBACK/SPAGAIN mess is by overly clever
attempt to optimize access to "global" variables which compiler
has a better chance of getting right by itself.
While on the other hand XS is forced to stuff everything on the stack.
My main complaint is that XS code is too unlike pp_xxx() and you
cannot easily call into pp_xxx().

Exactly.
