I see that in the last few weeks, [[:en:Template:lowercase]] has been updated to actually display the title in lowercase with a JavaScript hack. Any word on whether this is the long term solution to the problem, or whether the proposed magic word[1] will be implemented? Sorry, I don't know the relevant bug number.
Steve [1] I think we discussed this maybe a year ago, the idea of letting articles specify a "display" title. A first-letter-lowercase flag was the least controversial idea...
