>non-committal necessarily means shallow or inconsistent
No, it just means inconclusive, build up with no payoff, in other words bad writing.
The "shallow" and "inconsistent" parts come from your requirement to have a wide selection of pairings, which is something typically executed in either form or both, in order to keep all options viable without committing to any; harem is the textbook example of this, being the bottom of the barrel of yuri.
>the point is to be able to enjoy multiple headcanons
That may be the point for you, but people looking to enjoy a yuri work don't normally expect to have to look up fanfiction of it to get a satisfying experience, at least nowadays thankfully.
Even haremfag discussions mostly amount to predicting who's going to win in the end, and non-committal endings aren't usually well received, except by hardcore waifufags and I guess shippers like you.
>Ideally authors would write multiple versions of the same story
This is just personal but I would absolutely loathe this, just like I loathe alternate routes in VNs, if after reading a satisfying story about a pairing I've become fond of I go on to read another where one of the characters is paired differently, my immersion crumbles over itself, I'm forced to acknowledge that the first story I read didn't actually "happen", it was just some alternate scenario I was reading about, which demolishes my fond memories of it.
If tomorrow they released an alternate Madoka anime where she is paired with Sayaka, I wouldn't even watch one episode of it.
>I just value choice over having one forced
But that's the thing, an inconclusive work doesn't offer you a choice, it just ends prematurely so some amateur has to chime in and do the rest of the work themselves in a completely different format.
You just happen to like random headcanons more than the work itself.
