I think it should be that way for recent-enough IOS images.
Older versions required an explicit "ip route-cache cef" in the interface
config. (And there were more options, like "ip route-cache optimal" or
"ip route-cache same-interface", etc. etc. which contribute to the
confusion).
Cisco is slowly moving into the right direction: drop all switching paths
except CEF and process. Simplify the code, get rid of corner cases and
bugs.
(Maybe also rewrite all the interface counter stuff at the same time...)
