E.g. here https://github.com/mne-tools/mne-python/blob/main/mne/viz/backends/_abstract.py#L491. Why do methods of a Qt abstract object have the name of the object in them? i.e.

toolbar = _QtToolBar(...)
toolbar._tool_bar_add_button(...)

seems very redundant when

toolbar = _QtToolBar(...)
toolbar._add_button(...)

seems like it will do and will be much easier to maintain.

Maybe @larsoner, you have thoughts on this/a good reason for why it is this way?
