Don't you think you're being a little bit dramatic? The chances of anybody who isn't an ubernerd caring about XSLT's removal is exactly 0.
Or is your complaint here reducible to "changes in browsers can cause bugs, and bugs can harm consumers" for which the solution is "browsers must never change anything", which is of course also harmful to consumers (like when an xslt parser bug is used to steal my bank details)
When disagreeing, please reply to the argument instead of calling names. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."
The better phrased version of my criticism is that voice menus are generally not rendered using a web browser and thus deprecating xslt in web browsers cannot possibly affect them.
Nobody is killing xslt in general, just the web browser bindings.
