I agree with you, upgrades like that should fail `validate` when you
install the package, too.  And I have had several cases where EX-series
configs passed validation but, well, were not valid post-reboot.  Once
the whole box wouldn't function after reboot because mgd or something
similar was crashing due to a syntax change in the config file, so all
the interfaces were offline.

Juniper could stand to take notice of issues like this and improve the
validate process for several platforms.  I know it's not a substitute
for checking the documentation before an upgrade, but ... on EX this has
been a real problem between several various because of syntax changes.
