How come IAF, FAF, MM, MAP, are all depicted (usually) on the profile view
of an approach chart but the IF (intermediate fix) is not?

The purpose of the profile view is to depict any altitude change or
timing point. If the IF does not serve that purpose then it will not
be depicted. Some IFs are depicted on the profile view in LOC/DME
approaches.
