Yeah, if this was 1.9.0 and we'd been able to give some advance notice I think we might give it a try. But right now we're talking about making a big change in 1.9.1 which seems like a bad idea. 

We know we can go back to handling text nodes if we need to, so let's not rush to land a change to revert 2.0 yet either. I'd like to find out how common it is that people are doing this, even though it's unsupported, and what level of "support" it would take.

Even if we have to put back text node support in 2.0, I'd like for us to have a consistent set of support rules for text/comment/fragment in 1.10/2.1 and we have some time to figure it out.
