Not true. There are KMs in the 22" range. Mots are larger, yes, but there are smaller models available.
But other than that, you are right on most points. I have also seen KM pipes without a branded try too. It might have been a later replacement, but I remember seeing/hearing about some that are coming with pretty standard trays.
