Lack of dedicated documentation page for `Schema.extend`
Any reason why
Schema.extend has no documentation section yet? Is isn't marked experimental. It's since 3.10, so not that old. But, it took me a while to read Projections and Transformations only to realize it wasn't what I was looking for. I eventually stumbled by chance through LSP autocompletion upon Schema.extend. It has tsdocs, which is great, but it would have been nice to know the feature existed from the official https://effect.website/docs/schema docs.
