1157182254,I_kwDOBm6k_c5E-TMu,1646,Configuration directory mode does not pick up other file extensions than .db,15640196,closed,0,,,3,2022-03-02T13:15:23Z,2022-10-07T23:06:17Z,2022-10-07T23:03:35Z,NONE,,"Hello, I've been trying to run Datasette with the [configuration directory mode](https://docs.datasette.io/en/stable/settings.html#configuration-directory-mode) with a structure such as this one:

```plain
some-directory/
    example.sqlite3
    another-example.db
    one-more.custom
    [...]
```

(In my scenario I can't just change the filename extension without other problems arising)

Now databases with the `.sqlite3` or the custom filename extension are ignored by Datasette in this case. I'm aware that the docs state that a `.db` extension is required, but I was wondering if there is a reason for restricting this or any workaround available? When I run `datasette example.sqlite3` or `datasette one-more.custom` the databases are served by Datasette without a problem.
