Fix some issues with experimental config settings
Issues: 1. Features gated on disabled experimental settings should warn and be ignored, not silently succeed. 2. Experimental settings in the same config "batch" (file or env var) as the enabling of the experimental feature should work. 3. For (2), the order should not matter. These are analogous to the issues @roberth caught with my changes for arg handling, but they are instead for config handling. Co-authored-by: Robert Hensing <roberth@users.noreply.github.com>
