I have been several times since reopening. It is not "being allowed"--if CMs see it, they will intervene. We were in a long a winding line for HM and had already waited close to an hour when a CM caught some snackers in line and booted them out of the line. Have also seen numerous CMs chase down "walk-and-eaters" and stop them. Saw some people being escorted out of the parks, crying kids in tow. But of course, also saw cheaters get away with it. CMs can't be everywhere at once. But (1) that doesn't mean it is "allowed", you can be caught, and they may be severe consequences, and (2) the rules are there for a reason--other guests deserve an environment where everyone is following the rules and helping to mitigate the risk.
PMs are not necessary--it's not a secret and has been widely reported on the "Here Now and Just Back" thread that you will see people at Disney break the rules, and sometimes, they don't get caught. Sometimes, they do.
We are stating what is allowed, which is both based on the posted rules AND our direct personal experience of what can be, and has been, enforced. Surely, you wouldn't report that you saw someone cut in a line and therefore that means Disney is "allowing" it. Rule breakers exist, but doesn't mean the rules aren't enforced when a CM catches it happening.
