I believe removing jails cannot be done with just the config file and would
be a lot of work to do at all. That said, I wouldn't remove them even if I
could and didn't need them for isolating services: jails can also be useful
for a variety of "unexpected" purposes, such as building ports with
poudriere, poking at boot environments, or even playing with linuxulator.
On several of my systems, I have zero jails running by default, yet I
consider it useful to have them available when the need arises :-)
