@ploum @aaribaud @SylvieLorxu @LenticularCloud experimental: not really. My inclusion criteria are a little less strict, so I can cover apps F-Droid can't. And give devs a chance to "step up". So far almost 500 apps started in my repo have moved on to F-Droid exclusively.
And updates can get stuck if builds fail, e.g. because of technical problems with the code/build. Most of those fails are fixed quickly, but not all can. Eg a minor non-free component is not allowed at F-Droid but maybe here.
