If your vendors have issues with this, push them to fix it.

Is it really that hard?

Well, I don't think it's particularly easy. Generating the filters isn't the hard part, but getting them inside routers has always been quite a challenge. But that should be better than it used to be now.

By the way, you don't mention filtering based on routing registry information in your book. (I do mention it in mine but don't explain how to do it as I have never done it myself.)
