The zshparam(1) man page says:

    ! <S>  The process ID of the last command started in the background
           with &, or put into the background with the bg builtin.

but

zira% sleep 10 &
[1] 20475
zira% coproc sleep 10
[2] 20478
zira% echo $!
20478

I assume that coproc commands are also concerned by $!.

IIRC coproc commands did not, originally, get job table entries, and
although it has been years since they began to do so, the doc for $!
probably predates that.
