This is really at the crux of it.
With respect to you both, I disagree. I don't think that's really the crux of it at all.
Perhaps I'm coming at it from a different angle (not wrist angle, mental angle

). To me it's about this: Some folks are arguing that you should avoiding using one of your LH fingers (25% of your total supply) almost everywhere in the "money" area of the neck, whereas others are saying that it's worthwhile to practice being able to use all of your fingers equally well, or as equally as is feasible, all over the neck. The latter seems like a much more sensible idea to me.
One idea that seems to be getting lost here--and that is at the basis of tF's misunderstanding--is that learning OFPF is much more about inculcating the
ability to do something than it is about mandating that a given fret interval always be fingered a certain way. IOW, OFPFers are not saying that if you want to go from, say, F to G, on the low E, you must always finger it 1-3. They're saying that you practice doing it that way so you have the
ability to do it should you ever need or want to. They're saying that
you're better off if fingering it 1-4 is not the only way you are able to do it. There are plenty of times when an OFPF player might elect to use 1-4 for that sequence, depending on what came before and what will come after. I do that kind of thing all the time, and so do others. I also do it as 1-3 when that's called for. I know I've said this before, but watch a good classical guitarist. That's OFPF (actually sometimes more than one fret per finger) in practical application.
The thing is, if you practice OFPF, there's nothing stopping you from dropping into 1-2-4 whenever you feel like you want or need to. But I don't think it works the other way as well. If you avoid using the 3 by only practicing 1-2-4, I think you won't find it as easy to go to 1-2-3-4 should that ever seem advisable. If your 3 is underdeveloped, it won't be able to keep up as well. You don't know something that you haven't learned, and you can't effectively use a skill you haven't practiced to develop. It's easier to refrain from doing something you already know how to do than it is to suddenly start doing something you never learned how to do. Knowing 1-2-3-4 allows you to use fewer fingers if you like, because you've practiced all of them, but practicing only 1-2-4 is likely to restrict your ability to use 3, at least to some extent.
The argument from safety strikes me as dubious. I see no reason to believe that 1-2-4 is any safer on the BG than 1-2-3-4 (again, understanding that OFPF is not to be applied in the kind of rigid gridlike manner suggested in an earlier post). I see no difference in wrist angle at all. However appropriate sticking to 1-2-4 fingering may be for the DB, I see no reason why that should automatically make it preferable for the BG. The ergonomic issues are not the same.
