I like that they've started teaching difference between "fair" and "equal" in kindergarten now in Canada. This is not meant as a slight, just a generational gap - I myself was not taught that as a kid and it took me way too long to realize that "fair treatment" and "equal treatment" can be wildly different things.

Xcheck is, by definition, at its very core, not "equal treatment". Equal treatment is easy and uncontroversial to define.

It may or may not be "fair treatment". That is always subjective and depends on goals and objectives and frameworks.

Something like Xcheck may or may not be necessary. It's interesting to read about problem it's trying to solve and discuss whether and how much it succeeds and at what price and what limitations.

What Xcheck does not get to do, however, is present / defend itself as "equal treatment",and in any meaningful discussion we should not mix and match or treat those as synonyms - that's confusing and unproductive at best, deceptive at worst.
