It probably already is.
Not yet. I quite like 20.04 server edition, but right after installation I run a small script which starts like so:
apt-get purge -y fwupd packagekit dconf-service dconf-gsettings-backend bolt unattended-upgrades open-iscsi multipath-tools sg3-utils tpm-udev glib-networking glib-networking-common glib-networking-services snapd landscape-common
apt-get install -y zsh bc kpartx zip unzip wget curl tmux htop vim
apt-get autoremove --purge -y
The machines work just fine without snapd. It's a good luck that I have no desire to use LXD because then I would have to install it with snap.
