That's how the setting contest ended up playing out too. At the Eberron Anniversary panel, someone asked Bill Slavicsek what the other two settings were about. One was prehistoric D&D, and the other was a psuedo-Roman setting.
I did some digging. Microsoft announced the end of Silverlight support for Internet Explorer 11 in July of 2019. That must have been when they decided to start winding things down.
What's funny is there is an explicit mention of there being "half-dragon lizard folk" of Q'barra in the 3e Eberron book, but some people acted like it was beyond the pale to say, "yeah, those are Dragonborn, here's some more information about them."
Looks like this is where it's headed...
