I noticed the system MQTT topics may need to always be prefixed with the base. I'll check how it looks like in 3.4 and make sure its backwards compatible.

I checked with 3.4 and also b10 and none of the system MQTT discovery topics had the ems-esp prefixed, which is odd and probably wrong since a Home Assistant entity like sensor.system_uptime is a bit ambiguous. We can consider changing it later.

I'm going to merge the PR now as I'm worried people will install this b11 and mess up their HA

Nice idea to keep backward compatibility.
But it's an option only affects HA discovery, isn't it better to place the checkbox to HA section like this (and hide with HA disabled):

Yeah. I thought about that too after I implemented it.
