Unfortunately this means it may break other test suites that depend on `sqlite-utils` that have schema tests like this baked in.
I don't think this should count as a breaking change release though, but it's still worth noting.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1817289521,

add_foreign_keys: Optional[ForeignKeysType] = None,
# Or this one causes them all to be replaced with the new definitions:
foreign_keys: Optional[ForeignKeysType] = None,

There should be validation that forbids you from using `foreign_keys=` at the same time as either `drop_foreign_keys=` or `add_foreign_keys=` because the point of `foreign_keys=` is to define the keys for the new table all in one go.

At that point we have `foreign_keys_to_create` as the ones that are new, but we should instead try to build up a `foreign_keys` which is both new and old, ready to be passed to `.transform()`.
Here's the rest of that function, which will be replaced by a called to `.transform(foreign_keys=foreign_keys)`:

It turns out the `.transform()` method already has code that creates the new table with a copy of foreign keys from the old one - dropping any foreign keys that were specified in the `drop_foreign_keys=` parameter:
https://github.com/simonw/sqlite-utils/blob/1dc6b5aa644a92d3654f7068110ed7930989ce71/sqlite_utils/db.py#L1850-L1872
Improving this code to support adding foreign keys as well would be pretty simple.
And then the `.add_foreign_keys()` and `.add_foreign_key()` methods could be updated to use `.transform(...)` under the hood instead.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1817289521,
