Code review comment for lp:~maas-maintainers/juju-core/maas-provider-skeleton

Note about points 9 and 17:

«9) environs.HighestVersion in StartInstance [FIX unless not unique]

«This is wrong, but it might still match other providers.»

«17) flags := environs.HighestVersion

«crossgrading (9) to a changing-beyond-recognition»

It's still the same in the EC2 provider, so leaving this be for now.
