I look forward to your modifications to the OSM Carto (and other) 
stylesheets to add handling for "disused=yes" throughout then. :)

Your use of "always" above simply isn't borne out by the facts.  I 
personally have "always" tried to tag "former" things in a way that's 
appropriate to their current status, and that _might_ be disused=yes (as 
discussed in the thread above) but it might also be "disused:foo=bar", 
or it might be delete the tag entirely, while trying to keep some link 
to history (see http://www.openstreetmap.org/node/364520111/history for 
an example).
