Thanks for all the hard work.  Changing the message, however, does not
address my concern.

My issue is that substitute servers are queried too often---and possibly
for the same packages after they were already found somewhere else.

I have a lot of substitute servers because I run a custom version of
Eudev, which in turn rebuilds much of Guix.  Since I cannot, in general,
rely on the official substitute network, I cross-publish my stores
locally to minimize the local build effort.

Many system updates spend more than half the time on querying substitute
servers.  Changing the message does not address that issue.  Thanks!

Kind regards
Felix
