That somebody could have been me.  My understanding has always been that
a terminal will send ASCII char 9 when you type either the TAB key or 
C-i
(and similarly for the other special cases).

In GUI environments I'm sure the combination of the Ctrl key and "i"
can be recognised independently; but how could that work in terminals?

Or are you suggesting that an explicit binding for "C-i" would cease
to have *any* effect in a terminal, just like bindings for "<tab>"
won't have any effect, because Emacs would no longer recognise ASCII 9
as being "C-i"?  <tab>, C-i, and TAB would be three different things?
