No it won’t and I don’t know why you’re even asking that question because I never even hinted it was possible. Where did you get that idea from?
No one is going to “forget about it” because you clearly stated Tasmota has a “function to discover MQTT services” and used it to justify your Feature Request. However, the official builds do not support mDNS.
Feel free to make a Feature Request but don’t justify it based on a faulty comparison.
