Still no support for Lumix full frame lenses in Jpeg?

...or am I missing something? Recently bought a Lumix S1 with 24-105 and I don't often shoot RAW; in fact I haven't yet attempted to do so. Figured support would come with the June 2020 update, but apparently not. Is there an issue? Lightroom supports plenty of obsolete / obscure cameras but with the Lumix S series having as much as 10 percent of the hot mirrorless full frame market, I figured Lightroom would be on top of it. Do I need to move to a different processing platform?
