I attempted to answer that already.

"apt purge $package" uninstalls a program and deletes its global
configuration files.

"apt purge" delete all the remaining config files of any apps that
have already been uninstalled.

Ubuntu's new transactional packaging system.

Yes.

Well, I used to run Server 20.04 on a RasPi 4 and `snapd` was present.

I removed all snap packages, and then snapd itself, and  the machine
continued working fine but with slightly more free disk space and
memory. I also removed "multipath" as a single RP4 with a few USB3
HDDs on a single hub did not have multiple paths to any of its
devices, and the multipath daemon was prominent in "top"/"htop".
