I think it makes more sense to just put this at the top level (without stroked), unless there are additional variants not included here.

That's what I had originally, but my thinking was that it makes more sense to keep .stroked when there's also .filled. That's also how it is for e.g. hourglass.

Currently we aren't entirely consistent (which we ideally should improve upon), but in my mind it makes more sense when there is no canonical variant. In this case the stroked one is the canonical variant, and stroked just serves as extra noise.

Not to mention the big variants are variants of the stroked ones.

Remember that it's not required. Since stroked is the first variant, bowtie is automatically a shorthand for bowtie.stroked. A part of me thinks that users could be confused when some symbols only have stroked available as a modifier and some only have filled.

I know that it's not required, but I don't think that's a good reason to add unnecessary modifiers.

Notice how the unicode names mention "black" specifically, but not "white" for the regular ones.

I really don't want the added complexity of enshrining a "canonical version" for some symbols by means of omitting certain modifiers for them. That's another data point users will have to remember and seems like a totally unnecessary restriction. It's conceptually so much simpler to just have both modifiers for everything with those two styles, whether one of them is canonical or not.

I would say that having .stroked is more complexity, not less. Why should I have to arbitrarily have to remember which operators get the stroked, only because they have a filled variant? I do not like relying on fallback, because it's unpredictable and brittle to codex changes. Almost everyone who want these symbols will want the .stroked variants.

But fallback is a feature. If you choose not to use it, then of course you may have to specify annoying modifiers.

My view is that most changes do not affect fallbacks. When they do, we should be careful about it. And we should have a way to specify which fallbacks can be relied on, and which cannot (e.g., with the minimal modifier set proposal I link everywhere).

I agree having some symbols with "canonical version" and some without is annoying.

Why should I have to arbitrarily have to remember which operators get the stroked, only because they have a filled variant?

Beyond the fact that you don't have to know that (thanks fallbacks), I like that I can know there's a 'stroked' if there's a 'filled' and vice versa. So I think having stroked/filled consistently is a net win if we can sort out the documentation/symbol page to be clear that stroked is optional, and have it clear for us also in the sym.txt format (e.g. as implemented in #105).
