It all depends on what you really need. There are a bunch of us who need
"thin" jails - just like you describe it. And there are people who need
customized jails (which ezjail or jadm can provide). With pkg(8)
upgrading bunch of jails is an easy task, just go with:

jls jid | xargs -oI% pkg -j % upgrade
