Compatibility with the license doesn't change, just which licenses are
compatible. The license is a set of attributes that can work with other
licenses that have similar enough attributes to be deemed compatible.
While it is possible that there is severe miscommunication over a
potential compatible license, it seems highly unlikely, given the amount
of work CC and others put into figuring out compatibility.

That page is a reference point for ongoing support that CC is giving to
the license, to maximize ease of use. I am confident that there won't be
any loopholes found in a license listed there.
