Description

Version 15.29.0 introduced a breaking change by removing the public static methods SyncPromise::runQueue() and SyncPromise::getQueue() from GraphQL\Executor\Promise\Adapter\SyncPromise.

Cause

PR #1805 ("Optimize Deferred execution") refactored the promise queue handling for memory optimization.
That included the removal of several public methods, namely runQueue(): void, getQueue(): \SplQueue, and maybe others.

Impact

The removed runQueue() method is public and is used by external libraries, notably https://github.com/overblog/dataloader-php.

See: https://github.com/overblog/dataloader-php/blob/master/lib/promise-adapter/src/Adapter/WebonyxGraphQLSyncPromiseAdapter.php

Expected Behavior

According to semantic versioning, a minor version (15.28.0 → 15.29.0) should not remove public API methods. Either:

1. These methods should be deprecated first and removed in a major version, or
2. The new class should be introduced alongside the old methods with deprecation notices
