That warning just needs to become an error message as soon as possible. See: http://d.puremagic.com/issues/show_bug.cgi?id=4216 It's in my list of about 20 very small changes that I'd like to see ASAP in D2.
can you please create an small web-page (or blog, or whatever) to save your always (very most of the time) ideas, change request etc.
maybe splitted by D2,D3 - small, huge, evil ratings... and keep that up to date - so can refere better and nothing is lost in the huge mass of others posts in this newsgroup
