You have always had (and always will) have that choice; the ability to
disable automatic printer discovery has been present since discovery was
added with CUPS 1.2 (released back in 2006!)
But there is no way to tell from a stock OS print dialog if a given
printer identifier is local, remote, "secure", "hostile" or whatever.
There never has been, and I don't think there ever can be.
You want secure printing? Put the document you want to print onto a USB
stick, and plug it into an airgapped printer that is in a
controlled-access room. Even that's not necessarily sufficient, but
anything _less_ than that is clearly insecure and inherently untrustable.
