> Their own examples literally show that this isn't the case. Just look at the "filming" example, with the "m". In addition, their five fonts showcase shows that letters that "need space" can overbound.
They don't, it's an optical illusion. That's the whole point.
Read the whole text and/or open the example images which show the different versions of 'm' and 'i' side by side and measure their bounding boxes. Or open the fonts in a font editor.
They have all the same width.
Think about the implications if what you said were true. The font (or typeset engine) can't know how many pairs or triplets of these special case letter combos are in a word or a line. So you can't make sure a word stays the same width. It's impossible. There is no 'lookahead' the font designer can use to ensure this.
The only option really, to respect the grid, is staying inside equally spaced bounding boxes that are the core property of a monospaced font.

...or just making sure your immediate neighbors and yourself equal their previous total bounding box? "Needs space" glyphs borrow from "gives space" glyphs, but only in the immediate vicinity not in totality. Spaces are neutral characters.
