The introduction of Python 3 and SPeech Refactor will introduce backwards incompatible changes.

Describe the solution you'd like

As one of the goals is to bundle all backwards incompatible changes as much as possible, I propose removing all functionality that is considered deprecated. This includes:

• Directly importing validate instead of configobj.validate
• textInfos.Point and textInfos.Rect should utilize locationHelper instead
• braille.BrailleHandler._get/set_tether
• config.getConfigDirs
• config.ConfigManager.getConfigValidationParameter
• inputCore.InputGesture.logIdentifier property
• synthDriverHandler.SynthDriver.speakText/speakCharacter, when they survives speech refactor

Describe alternatives you've considered

Just leave the code as is.
