Not exactly. On the one hand, the italic version of times roman actually 
is a design by itself, so it can very well be seen as a typeface.

On the other hand, specific size was important for lead type (which 
doesn't scale) and bitmap font formats. With today's outline and hinting 
technologies, most fonts are designed to work at many different sizes, 
so the specific size is rather irrelevant.

Anyway, what we are looking at is to have media types for font formats. 
Typeface affects this only marginally.
