Do you actually know that is the case, or are you just assuming it?
There are many feasible implementations which would make it harder to add intermediate sizes. For example, the font selection code could return an enumeration from a fixed set, where the actual numerical values of that enumeration are arbitrary - adding a new value to that set would involve adding code at every place where that enumeration was used. Or, it could return an index into an array of font descriptors, and other code may make assumptions about the size of that array. Or, any of many other ways. Even if it does return a number which maps directly to the numerical size of the font, it could be that the units of that number are such that it doesn't have the resolution to represent intermediate sizes.
I'm not saying it isn't as you describe, just that unless you have actual inside knowledge of the code, you can't assume that it is - there are many other ways of doing it.
