The idea is that if they did so, the people using software running in the browser could continue to use XSLT with just the browser platform because the functionality would still be there with a different backend implementation, but instead that in-browser XSLT functionality is going somewhere, specifically, away.

Right but either way, the vulnerability exists today, and you're saying that whether or not the browser platform supports the functionality that harbors the vulnerabilities, the browser platform should be responsible for resolving those vulnerabilities. That's how I read it.

No, I'm not (and I keep saying this explicitly) saying that browsers should or should not do anything, or be responsible for anything. I’m not making a normative argument, at all.

I am stating, descriptively, that browser vendors choosing to remove XSLT functionality rather than repairing it by using an alternative implementation is very directly contrary to the claim made upthread that “XSLT isn’t going anywhere”. It is being removed from the the most popular application platform in existence, with developers being required to bring their own implementation for what was previously functionality supported by the platform. I am not saying that this is good or bad or that anyone should or should not do anything differently or making any argument about where responsibility for anything related to this lies.
