This is suboptimal because then your /nar responses lack the
‘Content-Length’ header (‘guix publish’ cannot provide that header when
running without ‘--cache’), which in turn means no progress bar, no
estimate of the amount of data downloaded, etc.

‘guix publish --cache’ should bring you the same benefits.  I’d still
recommend having nginx in front of it (for HTTPS, etc.), but caching can
be disabled in nginx in that case.  That’s what we do on
ci.guix.gnu.org.
