Because digital stuff is better to handle by dedicated hardware. This is
why I wrote that if you are using main CPU for the purpose of making a
signal generator or an incremental encoder or what you wrote below, it is
an architectural problem.

See above. I understand that hobby projects may do things one would never
do otherwise. But I doubt that there might be serious demand of such stuff. 

Imaging myself a hobbyist I would rather buy something like a small robot
with a decent CPU running Linux with WiFi, actuators, cameras etc, and only
if there is Ada 2005 available. 

Why didn't you take an RF TV remote receiver? It has USB/COM interface and
is fairly simple to use. We deployed such stuff in some projects.
