That should not be the case: Your metadata describes your SP,
independently from who's asking.

That cannot produce arbitrary customizations (you don't explain just
how your own metadata would have to differ for those IDPs) that way
and there's no trust in pointing anyone at the gerenator's URL.

If you had to produce varying metadata documents for a single SP, yes.

Why would the SP need to "know and use" metadata about itself?
It's (only) the IDPs that will need the SP's metadata.
