Submit the patch which fixes the recipe and removes the blacklist. As 
for a wide sweeping plan, I imagine recipes will get blacklisted until 
someone who is actively using them notices and submits the patch to fix. 
There isn't the time available to fix all the recipes and then run-time 
test them to make sure that the fix has actually worked.
