I have the Lumetri panel always open in a group of tabs, but it's not the panel that's shown/active (usually it's the Effect Controls Panel).

Often I'll need to tweak color using Lumetri for a slight exposure boost or white balance shift, so I click the Lumetri tab, make the edit, then click back to Effect Controls tab showing on top of that panel group.

But this still leaves the Selection Follows Playhead on and I have to go disable it every time.

The best would be a preference for this behavior - whether it's auto-enabled by Lumetri's activation or not.
