What kind of feature are you missing? Where do you notice a shortcoming of PTB?

The filters argument of the MessageHandler constructor is currently a positional argument and defaults to filters.ALL if None is explicitly passed:

Describe the solution you'd like

Using a keyword argument instead:

 def __init__( 
     self,
     callback: HandlerCallback[Update, CCT, RT],
     filters: filters_module.BaseFilter = filters.ALL,
     block: DVInput[bool] = DEFAULT_TRUE,
 ): 
  
     super().__init__(callback, block=block) 
     self.filters = filters

Or something similar.

Documentation could be improved as well:

Seems unclear to me when it is stating pass ``~filters.UpdateType.*`` in the filter argument.
