Adobe's tech documents are here:
"The showpage operator is permitted in EPS files because it is present
in so many PostScript language files. Therefore, it is reasonable for an
EPS file to use the showpage operator, although it is not necessary if
the EPS file will only be imported into another document. The
application importing the EPS file is responsible for redefining showpage."
So it seems that any problem you had with showpage was possibly the
importing application's fault.
I've just realised I've been hacking PS files for 15 years now...
