while --devmode is required for snaps that have confinement:devmode,
it can also be specified for confinement:strict, in which case you'll
have a non-confined (and soon non-auto-updating) snap that could be
confined. Useful if you're seeing weird behaviour in the snap and
wondering if it's because of a confinement bug, but not for much
otherwise.

The reverse is not true; if you have confinement:devmode and you don't
specify --devmode (or, in 2.11, override it with --jailmode), you'll
get an error telling you as much.

HTH,
