Having flashbacks of “<!--[if IE 6]> <script src="fix-ie6.js"></script> <![endif]-->”
Not sure how you got from that to “Google is ignoring standards”.
WhatWG is focused on maintaining specs that browsers intend to implement and maintain. When Chrome, Firefox, and Safari agree to remove XSLT that effectively decides for WhatWG's removal of the spec.
I wouldn't put too much weight behind who originally proposed the removal. It's a pretty small world when it comes to web specifications, the discussions likely started between vendors before one decided to propose it.
Users and web developers seemed much less on board though[1][2], enough that Google referenced that in their announcement.

I'm saying that I don't see any evidence that this was "driven by google". All the evidence I see is that Google, Mozilla, and Apple were all pretty immediately in agreement that removing XSLT was the move they all wanted to make.
You're telling us that we shouldn't think too hard about the fact that a Mozilla staffer opened the request for removal, and that we should notice that Google "led the charge". It would be interesting if somebody could back that up with something besides vibes, because I don't even see how there was a charge to lead. Among the groups that agreed, that agreement appears to have been quick and unanimous.
I am sharing my view, though, that Google engineers have been the majority share of browser engineer comments I've seen arguing for removing XSLT.
