Pyface is usable with multiple gui frameworks, requiring pyqt seems like an error. While it guarantees that one framework will be available, it can create conflicts (e.g., pyqt is 5-only, which requires qt-main, which conflicts with qt6-main so you can't currently safely use pyside6 with this recipe!)

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.
