The "snap for servers" was an issue so long time ago. I do not think it is worth repeating. Both snaps and flatpaks require a core image (a rootfs), and each package sits on top of that rootfs. For snaps, there is the core16 (and core18) images, which have quite a lot of shared libraries. Your snap package simply contains your program and any other extra libraries that are missing from the core image.
