As a programmer, that’s how I get work, and it’s the whole point of an API, the API lets you do things, that Website doesn’t support or intend to provide. That’s why programmers, such as myself, exist to solve the problems you have.
Twitch must have a reason for having a TMI timeout limit, but that doesn’t stop as programmers creating our own rules and programmed to achieve whatever a streamer wants.
This is somewhat false, some features are not implemented because they cannot be done well to support all the users of the site and/or other things have priority over user suggested features.
You are welcome to your opinion, but all we can do on the third party developers forum, is send you there for feature requests.
