It is not at all standard.  For example, GNOME does not offer anything
like that in its Window Preferences.  What it _does_ offer is a dialog

Window Selection

[ ] Select windows when the mouse moves over them

    [ ] Raise selected windows after an interval
    Interval before raising: [0.0-10.0, default 0.5] seconds

Deactivating any of those lines will deactivate the following lines.
The default is "off" for all options.

I actually know of no window manager offering a delay before select.
If at all, they have delay before raise.

Raising a window is an action that changes the window configuration,
so avoiding unintentional raising is a good idea there.  The
equivalent of window raising in Emacs would probably be something like
delete-other-windows (which we certainly would not want to do) or
other window-configuration changing things.

And unloaded machines and non-networked X11 connections.  But not
everybody is running Emacs on a machine of his dreams all of the time.
