Yes, I've used it in the past.

I don't use it because '&&' is not available. I use it pretty often.

Instead use:

    command1; and command2

It's not the same thing.

; executes the following command even if the first one fails. && only if the previous command returns 0.

Not when used with and. And and or verify if the previous command executed. It says as much in the documentation linked by OP.

So you can do things like: runthiscommand; and echo "Success"; or echo "Failed"
