Laminas Db Adapter Pool: Compatibility Boundary When Upgrading to Laminas Db v3?

Determine whether applications that currently rely on the Laminas\Db\Adapter\Adapter\Pool can upgrade to a future Laminas Db release without encountering breaking changes, given that the pool is marked experimental and its size cannot be altered at runtime.

The pool’s fixed size, lack of thread‑safety, and the absence of an official migration guide create uncertainty about its long‑term support. The documentation notes that the implementation may be removed or replaced in an upcoming major version, but no concrete timeline or deprecation warnings have been published.

Will the pool be removed in the next major release, is there a recommended alternative for connection pooling, and at which version will any deprecation notices appear?
