cl-dbi

The March 2020 update changed `dbi:execute` to accept parameters as a list instead of separate arguments, making older code incompatible and requiring manual updates.

Only supports SQLite3, PostgreSQL, and MySQL natively; other databases require implementing a new driver from scratch, which can be time-consuming.

Requires managing separate driver systems (e.g., :dbd-sqlite3) and explicit dependencies in system definitions for executable builds, adding to initial setup effort.

The abstraction layer may introduce overhead compared to using database-specific libraries directly, though this trade-off is not quantified in the documentation.
