Thanks Paolo! We'll do that once we have everything in place. For now Dave (the person responsible for Pi images) will do some tests to make sure we're able to handle all the upgrade cases. But what we think will have to happen is that we'd probably ask not to backport this change into bionic and xenial. With snaps lacking dependency handling, it would be too easy to actually cause machines to stop working - even if in our gadget snaps we support loading of both compressed and uncompressed kernels (with determining which case is currently needed), there's still the case where someone could update only the kernel and leave an old gadget snap. So we'd probably have to stick to uncompressed kernels for core18, only switching to .gz in core20.
