I've always wondered why ZODB didn't offer an option of storing the object index in a BTREE, but I guess its the performance issue of potential additional disk accesses.

This was one of the benefits of the Berkeley DB storage.  Sadly,
we put a lot of work into the BDB storage and people didn't seem
to care that much.  That, and the grief we got from Berkeley DB
itself made us drop the effort.  I do still think it has a lot
of potential.

We could make the file-storage index management more sophisticated,
but I'd really rather find something like the Berkeley database that
we could build on.
