@wolf480pl Heh, I think "unopinionated" cannot exists. There's choices that have to be made and there's also the fact that at some point software is written by humans, not some hivemind specie.

And even if say, we actually have an unopinionated implementation, being maintained forever isn't a thing.

Which is why I think it's a lot better to have a diversity of implementations than a monopoly or duopoly.
And reusability helps a lot there, specially because it often then allows to swap components either ship-of-thesus style (see Unix-like systems), or with switching to another dependency+API.
Like you can move from GTK to Qt, and probably will be able to move from WebKit to Servo. But move from being a Firefox fork to being a Chromium fork? Probably not.
