Different fonts offer different ligatures, and if I want to select a subset the font itself provides variants that let me do this. Meanwhile, I hope that we can make Emacs act like browsers or other editors in that if I select a font it will just, by default, use the ligatures that this font provides according to the logic embedded in the font.

I agree. We should let them control the logic, but that doesn't mean we have to force them to do so; which means we need a way to extract that logic, somehow. My udnerstanding was that it could be quite complex, so there was no point in re-implementing it in ELisp.
