PyQt6 support has been removed due to multiple issues, including incompatibility with Qt Designer plugins, discrepancies in test writing, and differences in signal-slot signatures.
However, we continue to use qtpy
to maintain abstraction, allowing for potential future re-evaluation of PyQt6 support if needed.
