Hmmmm - I'm not so sure.  I've always found spirit compilation times to
be very, very long.  Even it were reduced to just very long they
would be "too long".  The real solution is just isolating them into
something that is only compiled once  - i.e. a library or DLL.  Then
the compilation time is a non-issue.
