Typical slashdot over-reaction ;)

The bug wasn't fixed earlier because:
1) it's like it is the only open bug report, you know... this is just one bug, which happens only with advanced usage,
2) the bug was default-assigned to someone who left the project since, so the people who could actually fix the bug (e.g. me) didn't see it.

It took me a full day of very intense and complex debugging to fix this.

Typical slashdot: the article distorts the truth in order to get reactions.

It was pretty clear during that presentation that the goal was to make it possible to still run X applications -- using a rootless X server -- and that this would also allow X-over-the-network use cases.
X11 is not going away, the idea is to use Wayland -and- X.
