This is I think true, but then again, TCP/IP fell into some of those holes
too: fragmentation for one (although the issue there was unforseen problems in
doing it, not so much in it not being a real issue), all the 'unused' fields
in the IP and TCP headers for things that never got really got
used/implemented (Type of Service, Urgent, etc).
