New Acrobat experience still crashing 3rd party plug ins

I am talking about New Acrobat as described here:

In a prior version of that page, there was a note about it not supporting 3rd party plug-ins. It wasn't very polite about that either; it just crashed with the plug-in installed but didn't if it was removed. It also runs fine with the plug-in in the regular mode.

The current version of the above linked page describing the new look doesn't mention the lack of 3rd part plug-ins. It was very prominently mentioned before and has now been removed, so my assumption was/is that they think it is fixed. 

What makes this especially bad is that when you get an update including it, it is enabled by default, so all users get the crash.

I am now wondering if this was addressed and there is something I need to change in my plug-in the support the new look.
