I think this sharing dropped off drastically at some point in fairly
recent history. I took a look at Apple's list of services and devices
which can be shared with a checkbox or two; it really was a much
shorter list than I thought, and I'm sure the most convenient Linux
distro has a couple less items again.

Windows I'm not so sure about, but I don't think you have to go back
many years to find the time when Windows 98 was the most common
Windows, and what did that offer to share? Printers and files only,
if I remember right.
