my biggest point for not allowing AGPL and proprietary module to cohabit is the legal risk because of this feature that is central to the Odoo framework:

That is if for instance I create a proprietary e-commerce module where a sale order can be placed. Then imagine there is a button that create an invoice from the order. Despite that proprietary module may not explicitly depend say on localization X that is AGPL, technically speaking in its code there will be something like sale_order.create(...).
Then this is the Odoo framework itself that will call any method overriding the original create method even if the proprietary e-commerce module doesn't depend on them. That is, in country X the proprietary e-commerce module will take advantage of localization X (say tax computation, correctness of the fiscal documents...) without technically depending on localization X. This also creating common structures n the same memory space inside the same operating system process, what is called by the *GPL "static linking".

If that would have to go to court, this is I believe the point where people should insist on.

Now, about the mix in general. Before with the AGPL, the community and even Odoo SA could discredit and kind of commercially blacklist any SaaS offering featuring non released modules and keep that pirate offer very marginal.

Now the problem with the new licensing sh*t is that one will hardly prove how exactly AGPL and proprietary modules interact exactly on these opportunist SaaS platforms to happen. So typically, in some countries with strong IP law enforcement, big players will eventually refrain themselves from taking that legal risk. Mostly the victims will be the official Odoo partners who will expose them to being banned if they do so without even things to have to go a court while their unofficial competition will certainly do it. Nice time to be an Odoo partner as some mentioned...
On the contrary, in many other countries, fearless outsiders will certainly derivate AGPL modules into proprietary modules. And they will also certainly make their way to approach the Enterprise modules (via fake customers or temporary partnerships etc...) to also offer clones of the Enterprise modules too... And even companies larger than Odoo SA themselves may play that game... So IMHO not even Odoo SA will benefit from this license change...

As I always told we all just lost a good opportunity to have a sane eco-system. This is a whole new area of dog eat dog beginning now...

I think there are many authors of AGPL-modules that don't want their 
modules do be mixed with non GPL-modules. That is the purpose with AGPL.
