At least on my Macs I can easily observe it. I don't care it because
I know it's harmless, but some users would be worried by it.

But the latest Terminal.app (macOS Tahoe, TERM_PROGRAM_VERSION=470)
already supports truecolor and recognizes the TQ_RGB, so +q524742 is
not printed. There should be no problem when Apple includes the next
release version of zsh (with termquery) as /bin/zsh in the next
(or later) version of macOS.

Users who install dev-versions of zsh by themself are not
'ordinary users', I think, and hopefully they will mange to find
it harmless, or set .term.extensions in a start up file.

On macOS, Apple's /etc/zshrc uses 'bindky' that requires Zle. So we
need to use ~/.zshenv, maybe in a block 'if [[ -o i ]] ...'.

Another problem is 'is-at-least 5.9.0.3  5.9' returns true
(workers/54336, or workers/47314 by Daniel).
This can be overcome only by installing a fixed version of
is-at-least (for example in /usr/local/share/zsh/site-functions),
or resorting to a hack like this:
