Nope.
My shadows did not revert to looking bad. I'm at a shadow distance of 4000. Plus, as I've said a bunch of times now, decreasing my shadow distance introduced severe hitching when riding on horseback through the mountains. That solution is terrible.
This solution actually works.
You're wrong. Your shadows did not go back to looking horrible, but they didn't stay looking the same as they would have at 2500. The "fix" in this thread helps, but the single biggest factor in how shadows look is fShadowDistance and that's a fact.
Take a screenshot of your shadows a 2500, then at 4000...they won't look as good at 4000. Now take one at 8000 and they look even worse. Even with all of your Shadowmaps a 4096 shadows still degrade over distance the higher the number.
I'm glad your shadows are looking better, but this fix isn't going to help all the people who have already had their Shadowmaps at 4096 and still have blocky shadows because their shadow distance is too high.
This fix does nothing without the right fShadowDistance setting.
