I'm building a UI for [Datasette](https://datasette.io/) that lets users make schema changes, so it's important to me that the tool work in a non-surprising way -- if you ask for a column of type X, you should get type X. If the column or table previously had CHECK constraints, they shouldn't be silently removed. And so on. I had hoped that I could just lean on sqlite-utils, but I think it's a little too surprising.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1572766460,

That might be a design choice to make it accessible to users by providing a reasonable set of defaults, but it doesn't quite fit my use case.

It might make sense to extract a separate library that provides just the mechanisms, and then `sqlite-utils` would sit on top of that library with its opinionated set of policies.

That would be a very big change, though.

I might take a stab at extracting the library, but just for the table schema migration piece, not all the other features that `sqlite-utils` supports. I wouldn't expect `sqlite-utils` to depend on it.

Part of my motivation is that I want to provide some other abilities, too, like support for CHECK constraints. I see that the issue in this repo (https://github.com/simonw/sqlite-utils/issues/358) proposes a bunch of short-hand constraints, which I wouldn't want to accidentally expose to people -- I want a layer that is a 1:1 mapping to SQLite.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1572766460,

One challenge is that would be a breaking change. Do you see a way to enable it without affecting existing users or bumping the major version number?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1572766460,
