And I think this was always communicated as the wrong approach, even
though the software allows for it. Mainly because it doesn't scale
well and reloading the whole metadata provider configuration is a more
heavy-weight operation than reloading individual metadata providers
(as in: one metadata provider with all your non-InC SPs in it) or even
never reloading anything at all (as in: using localDynamic).

Found via IDPv3 home -> Configuration -> Metadata -> "Search Ordering".

Depends on the desired effect and how much you trust your own metadata
curation skills, I suppose.

E.g. I put the MetadataProvider with locally managed SPs before the
federation metadata, because I want to be able to potentially override
what's in the federation metadata (for debugging purposes) and by
removing my local copy the federation-managed copy takes over.
