I too am a bit disappointed the old school approach towards interoperable standards appears not to be en vogue, but the Internet is a different place these days. However, back when we did the 5011 vendor tests in 2014, all known 5011 implementations seemed to work fine if they were configured correctly.  The interesting bit is figuring out if things are configured correctly before the attempted roll...
