Well, if you mean "as an official C++ syntax" then I agree, and I suspect Sutter would agree as well. He labeled one talk about it a "Towards a Typescript for C++", after all[0].
But I do think it is different than other "compile to C++" languages, because it seems to be more of a personal case study for Sutter to figure out various reflection and metaprogramming features, and then "backport" those worked out ideas to regular C++ via proposals. And the latter don't have to match the CPP2 syntax at all.
In multiple examples he's given in talks the resulting "regular" C++ code is easier to read, mainly because the metaprogramming deals with so much boilerplate.
