It's not in case of C-L. For a starter HEAD is used by quite many robots
with simplistic caches to verify that the copy they have is current and

The RFC is quite strict that entity headers of a HEAD response SHOULD
match those of a identical GET request, so difference in C-L is not
acceptable by the RFC. (T-E is transport, and may differ)

It's a pity T-E gzip isn't deployable. Would eleminate this whole
question as it's not an entity transform..
