I'd like a definition of what "unused" means (I know because of this
series, but I wouldn't know just from this document).
It means that it hasn't been accessed in that interval (because it
was not needed). Are you thinking of any other possible
interpretation?
Well... To me, intuitively, "unused" entries in a cache are just empty
entries. Just replacing one occurrence of "unused" by "not accessed
during the past interval" or something like that would resolve the
riddle for me. :-)
Ok, I see what you mean... I used the same wording in the
block-core.json description and in the .help field of the
cache-clean-interval option.

Do you want me to change those as well or is it enough if I clarify it
in this document?

I think it should be fine just doing it here, because if someone is confused by the QMP documentation, they can fall back to this document.
