The comment-block lint (added in 79dc8ca6) now trips on this block —
genuinely pre-existing, unrelated to that change, just newly caught.
Per the lint's own suggested remedy: relocated the full per-directive
reasoning plus both footguns (session-cache keying, the Host-header
clobber that can recurse a subrequest into itself) to a new
"Dialing another vhost by name" section in docs/gateway.md, and left
a short why + pointer comment in the source. No behavior change.
