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

Currently, the CallbackQueryHandler in the library only checks the .data attribute when handling callback queries (ref). This presents a limitation as it doesn't support regex filtering handling clicks on buttons associated with CallbackGame. When a user clicks on a CallbackGame button, the .data attribute is None, causing the CallbackQueryHandler's regex pattern match to fail if it is set.

Describe the solution you'd like

I think changing this line to

callback_data = update.callback_query.data or update.callback_query.game_short_name

would solve this limitation.

Describe alternatives you've considered

Currently I manage to overcome this by handling all callbacks in one handler without pattern match and then using if else with .game_short_name attribute
