Certainly it could happen again. However, the new rule is designed to keep aircraft from switching from one level to another in the middle of the corridor. The helicopter would stay low until either Alpine Tower or VZ and the airplane would stay high until either of those points. If the airplane pilot had wanted to join either the "transient" or "local" levels, he would have already made that decision and change to the CTAF frequency. I think that the controllers in the neighborhood of the Hudson corridor are sufficiently alerted (at least for awhile) to the dangers that they will positively assure informed entry into it.

Let's hope you're right. I hate to suggest the tour helis should be restricted in any way, but they can afford to stay lower, and it would be best if they did, for all concerned. The views of Manhattan are awesome enough from 900 feet; it won't hurt their business.
Personally, I've never had a problem with aircraft climbing or descending in there... most transiting fixed-wing pilots seem to just stay as high as they can, for obvious reasons.
But there's the jokers who are not using the CTAF and suddenly turn around in the middle somewhere... things like that are not a good idea in there.
It happened to me once , northbound in a 172, abeam the WTC- I was gaining on a C150 that was also headed north, way off on the eastern edge of the corridor. Couldn't pass him on the right without busting the airspace or the clearance rules, couldn't climb, and I didn't fancy diving under him (plenty of helis around, as usual). Soon it was at my 1 o-clock, a bit higher... I called and called to them, but no answer. Checked to make sure, again, that I had the right freq... called for a radio check, got an answer from somebody... so it wasn't me. I thought of passing on the left, but what if they turned?
Throttled back to avoid passing them, and waited to see what they'd do next.... I was glad I did, because they suddenly racked it over into a left 180 right across the river, as if they just realized where they were or something.

It was hardly a near-midair, but if I hadn't been vigilant... who knows?
Did that pilot check their 7 o'clock before turning? I'll bet a dollar they didn't. Probably had no clue I was there.
Requiring comms in the corrdior is hardly a bad idea... but as in the case I mentioned, it takes more than that to be safe in such an airspace- or anywhere, really.
