Indeed I remember that conclusion from the 2015 thread. If the fraction
formatting facility is available, it should be used. If it isnʼt, Iʼd suggest
not to leave the ASCII fallbacks, but to use super- and subscripts instead.
This still seems an overall second-best solution, that may turn into best solution
depending on the font used. If Arial Unicode MS is used (though it is no longer
a part of new Windows versions), it really looks exactly like preformatted
fractions in the same font. But I can understand that denominators are meant
to align on the baseline, while subscripts are often set slightly below.
Though sometimes suboptimal, “styled” plain text custom vulgar fractions still
offer a far better readability than their plain ASCII fallbacks. To be consistent,
fractions could be represented throughout this way in a given document, avoiding
the mix-up of preformatted fractions with precomposed fractions.
