Does this help with DuckDB concurrency? My main gripe with DuckDB is that you can't write to it from multiple processes at the same time. If you open the database in write mode with one process, you cannot modify it at all from another process without the first process completely releasing it. In fact, you cannot even read from it from another process in this scenario.

So if you typically use a file-backed DuckDB database in one process and want to quickly modify something in that database using the DuckDB CLI (like you might connect SequelPro or DBeaver to make changes to a DB while your main application is 'using' it), then it complains that it's locked by another process and doesn't let you connect to it at all.

This is unlike SQLite, which supports and handles this in a thread-safe manner out of the box. I know it's DuckDB's explicit design decision[0], but it would be amazing if DuckDB could behave more like SQLite when it comes to this sort of thing. DuckDB has incredible quality-of-life improvements with many extra types and functions supported, not to mention all the SQL dialect enhancements allowing you to type much more concise SQL (they call it "Friendly SQL"), which executes super efficiently too.
