Is the 'Secure attention sequence" useful on Linux in

Supporting what people are used to is valuable in its own right, but
is there any security advantage to users using a special sequence to
commence unlocking in GNU+Linux?
I'd personally not want to use it because I've seen too many GNU+Linux
systems get rebooted by a C+A+D that was intended as a SAS.
Sorry, I wasn't talking about a secure key (we don't have one) but rather
pressing a key which doesn't actually _do_ anything in order to clear the
screen. In olden times, sometimes when you pressed "enter" to clear a
screensaver, you'd accidentally also say Okay to some dialog box underneath.
The shield doesn't do that, but there's still a risk of it happening if the
system is busy and slow to respond and you hit an "active" key several times
in a row.
