Nope.
There's 'confusion', at the very least, around Manson's language in the injunction. It goes to the balance of convenience test as specified in the SJS case, and involves the sphere of the will of parliament (which is iffy because the MMPR didn't go through parliament).
However, the ruling is clear. Patients now have a codified, constitutional right to grow. This does not involve LP's at all, and if the LPC drafts bad legislation it will be back in court.
This is big trouble for the LP's. Now that people can grow, their revenue model just disappeared. To be constitutionally viable, the new legislation must follow Phelan's ruling, and the LP's have sweet fuck all for protection.
So no, they do not have to give any special weight to LP's. If they can't survive in a free and fair market, too bad.
Also, arbitrary regulations are exactly what this case was predicated on (and won), so yes, that is still restricting access. The LPC is of course free to write more bad legislation, but it will be back in court (and easily won).
