... and hope your CO is up to date.
Here is the regulation now in effect; see Table 9.

I think it's good that your local CO (at least) isn't planning to charge anyone under a regulation passed partway through the season. But it's not true that these are "recommendations." The regs change is in effect as of April 1.
That matters ... if someone in some other WMU takes your word for it that he can hunt 'til June.
Looks like the MNR has made an utter mess of this. Half the world convinced it's an April Fools' joke, and their own COs not informed the regs changes have been made and this is no longer a proposal.
