If separating out the various terrain draw distances won’t happen for MSFS2020, then I desperately hope it will for MSFS2024.
Having nearly everything tied to the TLOD slider is a backward step from what we had in previous Microsoft flight sims and a massive restriction on users whose PC setups can support higher quality in closer LODs.
As for the regression in satellite textures from the highest available quality at TLOD 200 (described here), this is another issue that can only be addressed by separate terrain draw distance settings.
