I put this in a parallel thread, but maybe this is a linguistic gap between "servant", a person who does what they are told and has very limited agency within the bounds of their instructions, and "service", where you do things for the benefit of another entity.

None of the above reads like a "servant-oriented mindset". It reads like "this is the framework by which we decide what's valuable". And by that framework, they're saying that keeping XSLT around is not the right call. You can disagree with that, but nothing you've quoted suggests that they're trying to prioritize any group over the majority of their users.
