Trying to read between the lines here, if your objection is to half-pixels because they’re not precise enough for (good) physics, then I apologize for being unclear - I mean half-pixels, or quarter-pixels, or eighth-pixels, or whatever.
Another way of wording my comment is that I think it’s easier - especially for beginners - to think in terms of smaller units (represented as integers) than in terms of a new number format for representing fixed-size fractional parts of larger units. But the two concepts are ultimately the same.
