Nice! About time they fixed something, amirite? I've noticed this behavior in some cases myself, but I always thought it was due to my using an external GPU (Razer Core X I think, with a Vega 56)...
Speaking of, have you ever had a situation where, without warning and totally random - even while idle - your Mac just goes APESHIT with the fans, instantly clicks into super overdrive cooling wise, and then shuts down? Because I've had that in the past and if this fixes that...well...I may do the happy dance. And I hate dancing.
