Agreed. That is a very good point about it possibly being just a digraph and not always a diphthong. This depends, however, on the use, since it does sometimes slide and other times is just a ligature. The issues seem to stem from the pronunciation changes and the great vowel shift. As you point out, language is a messy business.
In English, I'm pretty sure the ae digraph is always pronounced as /i/, so calling it a dipthong would probably confuse most people.
