Yes.  This has always been the case.

Indirectly, yes: shutdown(8) sends either SIGINT, SIGUSR or SIGUSR2 to
init(8), which runs /etc/rc.shutdown before killing all remaining
processes and either reboot / halt or start a single-user shell, while
reboot(8) and halt(8) send SIGTSTP to init(8), then SIGTERM to every
other process in the system, then SIGKILL to any process that hasn't
responded to SIGTERM after somewhere between five and sixty seconds,
before issuing a reboot(2) syscall.
