That would be terrible. Users not understanding the concept would suddenly be facing images where they can just save to JPEG while others can't, but PNG is still enabled (because they somehow added an alpha channel), and even other images support XCF only (maybe because the layer is bigger than the image).
(I used "just" in the sense of "without any further actions" and not "only".)
No, that's not what I'm suggesting. If you import a jpeg for example, do your editing, and end up with an alpha channel somehow, the save could still default to the .jpg (the jpeg save dialogue could display a warning that transparency will be lost). That does not prevent the user from requesting a .png (by specifying that extension). It also does not prevent the user saving as an xcf either for that matter. When closing the file, if the file is not saved as an xcf, and there is extra data to be lost, well, the warning about it is there anyway.
But that would mean to just go back to the status quo ante, i.e., revert the save/export dichotomy and bring back saving to arbitrary formats. [...]
