Awhile back a rumor went around that the COW frowned on the use of robes, as it supposedly created a disparity between those lodges that had them and those that didn't, and thus created a breach in the uniformity of ritual.
I could totally picture someone saying that, ugh! So because most lodges do not give long form lectures, will someone take exception to long form degree lectures being given because it creates a disparity? Oh wait, they're already frowned on in the name of "keeping it simple". Arguably, the CoR snafu really gave the practice a black eye, but other things seem to get "knife and forked" for not much good reason.
