I wouldn’t contradict your sentence saying “It may be more practical…”
However, the implementation of swing in Encore (4 or 5) is quite elementary – and even presents an incoherence between the Win and Mac implementation (or perhaps just the documentation).
Normally, the swing ratio should be preserved for a while, though mine seems blocked on 75% – which is not the default.
A swing ration of 66% is most common – for swing notation. Many pieces who are actually swinging at 75% have it explicitly notated with dotted eights- sixteenths pairs (or multiple).

Now, if Encore 6 comes some day to light, we should not expect that it resembles Encore 5 up to that level of detail. And before that hypothetical moment, it does not help to speculate.

There is a risk to see a swing implementation as basic as in Overture (eights at 62.5%!)
