No, I think it is not a good idea. A typical user would
not see a reason to use the option "cache". A lot of
explanation has to be written to explain this an user,
but users do not read documentation.

Why pdfTeX cannot collect the pages of the same included
file and adds only the needed resources at the end of the
pdfTeX run. Then an end user has not to deal with
extra commands "\pdfembed" or extra options "cache".
