One interesting aspect is that VFX 5.x finally includes an FP package
by default, and it started by including an SSE2-based FP package which
supports a deep FP stack.  However, MPE received customer complaints
about the lower number of significant digits in SSE2 (binary64)
vs. 387 (80-bit FP values), so they switched the default to the
387-based FP package that only has 8 FP stack items.  Apparently no
MPE customer complains about that limitation.

AFAIK x87 hardware stack was always MPE's main and best supported FP
package.  As for SSE2 it wouldn't exist if industry didn't consider
double-precision adequate.  My impression of MPE's SSE2 implementation
is that it's 'a work in progress'.  The basic precision is there but
transcendentals appear to be limited to single-precision.  That'd be
the reason I'd stick with MPE's x87 package.  Other reason is it's now
quite difficult and error-prone to switch FP packages as it involves
rebuilding the system.  The old scheme was simpler and idiot-proof.

 
You do not have to rebuild the system to switch. Just read the manual.

If you mean:

  integers
  remove-FP-pack
  include FPSSE64S.fth

That works - however everything that was defined after VFXFORTH is gone.
In the case of Windows at least it leaves the system in a fragile state.
I did find a way to recompile the forgotten stuff but it involved editing
paths and files etc.
