That's an issue for full 1788 (where we have rational literals). It does
not arise in 1788.1 where all implementations use (or appear to use) b64
endpoints.
The trouble with rationals is that there is no natural limit to p and q,
and they could be a Continued Fraction approximation of a b64 rounding
threshold, making it difficult to return the correct (tightest) hull.
If (as Dima asks later) the result of conversion were relaxed to just
"accurate" this would not be an issue.
