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

In some situations, it may not be possible to know if you should use update.message.reply_text or update.callback_query.edit_message_text. This could happen if user can start a conversation from different stages of a conversation (where sometimes they are using an inline keyboard and sometimes sending text.) IF it happens, you'll face an exception.

Describe the solution you'd like

I think it would be useful to have a function in update, that decides automatically if it should use update.message.reply_text or update.callback_query.edit_message_text. This could even be a simple try except block such as this:

def send_message(update, text, reply_markup=None, parse_mode=None):
    """
    Sends a message to the user.
    This will use callback_query.edit_message_text as priority. if it doesn't work, will use message.reply_text instead.
    To be used when we're not sure which one will be needed.
    """
    try:
        return update.callback_query.edit_message_text(
            text, reply_markup=reply_markup, parse_mode=parse_mode
        )
    except:
        return update.message.reply_text(
            text, reply_markup=reply_markup, parse_mode=parse_mode
        )

Additional context

This may also an issue for accessing from_user, but I haven't checked the docs to see if there is a solution for that or not.
