You are very thorough and systematic and your students are lucky to have someone who cares about details.
I would like to share with you an idea about scales taught to me by Steven De Groote. He liked to finger parallel scales so that the thumbs play together. The big problems in scales are to get them smooth, without bumps, and to keep the hands perfectly together. The turn over/turn under is hard. If you align the fingering to play both thumbs together, it gives you a little more of a fighting chance.
Your article notes that a B-flat major scale has no meeting point of the thumbs. That's true with the traditional fingering. However, you can make the thumbs meet if you wish to. In a parallel B-flat major scale, Steven would put his left thumb on C and F.
C major would have the left thumb on C and F, D major on D and G, etc. This isn't dogma. It's just a choice if you have a passage that has a long scale or even a fragment that could benefit from getting the thumbs together.
It's not traditional. I don't teach children, and I don't know when it would be appropriate to introduce them to such an idea. I learned that in college.
Interesting idea! Another one I've heard about is using C minor type fingering for E flat,so the thumbs land on C together. Presumably that could also be done with constant meeting of thumbs on C and F too though. Most of the variants I've heard about before are geared around turning onto black notes whenever possible- which gives some truly bizarre coordinations when playing unisons scales. I find such fingerings pretty useless except as a variant to use in individual hands (certainly not as a variant for unison playing), but it's interesting to think about way of keeping the thumbs together even in those that normally work differently.
As far as teaching students goes, I think I'll probably stick with traditional fingering for those two, but I do like the idea of having variants with extra thumb reference points. I think the thing about traditional fingering for those is that it's physically slightly more comfortable when doing the left hand on it's own (I depart from traditional F sharp minor fingering because I'm not convinced there's any advantage at all, even when playing the left hand alone), but I like the idea of extra thumb meetings. In fact, it might also be useful as a kind of "backup" fingering for students that greatly struggle to grasp the coordination for the traditional fingering on those two I'll have to try the extra one for C major. I think I might find it very odd at first (even though it's scarcely different to F major), but it definitely sounds worth experimenting with.
Your post also reminds me that I should probably write a simple explanation of arpeggio and broken chord fingering sometime too. So many people struggle with these, but it's very simple when the logic of where the fingering comes from is understood. In the ABRSM syllabus, for some bizarre reason they don't always line the thumbs up in arpeggios. In the case of arpeggios it seems like absolute madness not to work around thumbs that meet up (at least in unisons). They also start flat keys solely in root position- rather than train the feel for positions by starting with first inversion. It's a really stupid case of putting the cart before the horse- in a way that disguises the fact these keys are scarcely harder than those that start on white notes.
