This was implemented:

    EDS: create new databases by cloning the builtin ones (FDO #64176)

    Instead of hard-coding a specific "Backend Summary Setup" in
    SyncEvolution, copy the config of the system database. That way
    special flags (like the desired "Backend Summary Setup" for local
    address books) can be set on a system-wide basis and without having to
    modify or configure SyncEvolution.

    Because EDS has no APIs to clone an ESource or turn a .source file
    into a new ESource, SyncEvolution has to resort to manipulating and
    creating the keyfile directly.

The "openismus work" branches already include a suitably patched system DB, so
I consider the issue resolved.
