Keep in mind that other then Reg & Cert airports radio is not required "legally". So what is best practice comes down to opinions, I accept that, but if submissions are ignored (and maybe most submissions were in accordance with your opinion) remember a CAAP is only advisory not a CAR or CASR.
I find interesting V4 is released, as DJ pointed out, before the submission expirery date.
Reminds of something else, but better left unsaid.
