If this were a mandate, it would be a hassle, for any build that's
more than one directory wide.

OK, will add a cautionary blurb to the man page.

IMHO, even the former seems okay and even desirable:
debuginfod -F /usr/lib/debug
is a safe & easy way to relay the contents of all the debuginfo rpms
that were installed, to nearby clients. All those binaries come from
packages/distros, so are at least as high quality & trustworthiness as
the user's own. Again I offer to do an audit of some distro debuginfo
that all their source refs are milquetoast like /usr/include or
/usr/src/debug.

ca-certificates.crt types of files (or /usr/share/pki/ files) are the
trust roots for validating the *servers'* certificates. They are
generally provided by the distro, so can't possibly serve as unique
*client* authentication.
