Probably the ones I'm rooting for the most are Allegiance, Houdini, and Dames at Sea. Allegiance because it appears to be a powerful story and one that needs to be told. Houdini I'm rooting for less now that Jackman is out, but I'm still excited for a new Schwartz score. Dames at Sea because Laura Osnes and Rachel York are awesome!
You're comparing apples (anticipated productions) and oranges (properties in development).
Your list of properties "in development" would be hundreds of pages long. Practically never-ending. That is NOT what Playbill's list is. This list is discussing musicals they anticipate coming to physical fruition in the near future.
ETA: So, for example, the musical version of Mean Girls would be a property in development. Not a musical anticipated on receiving a physical production anytime soon. That is why they are not on the list.

And those are the ones that just came to me immediately.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
But if I read the OP correctly, that list is of properties that are soon receiving a full treatment (Broadway production). Not of properties that are "in development."
That is why 'many, many are left off' and 'ya'll just forgot about The Princess Bridge & The Muppet's.'
And while we're at it, can someone contact Playbill and get Rebecca off that list? You know and I know that it ain't never gonna happen no matter how hard Ben Sprecher tries to fill the escrow account.
