IIUC what you mean by "this feature", we already have that in
latin1-disp.el. It just isn't automatic, because most terminals and
terminal emulators don't have a way of reporting which sequences they
are capable of composing. So we let it to the users to determine
whether they need this kind of "ASCII-fied" display.
I asked whether adding a command that specifically targets ligatures
like "fi" would be useful -- can you answer that?

Given the enormously large number of such sequences, I doubt that
terminfo is the right means for determining which sequences are
supported. We have a solution for the Linux console, and for the rest
we allow the user to customize the value of auto-composition-mode to
disable it if the terminal misbehaves with these sequences.
