I shared the answer for all your considerations, but just few people can recognize what the solution is:
BIM HAS BASE ISSUES
BIM has some base issues that even repeated in ISO 19650 that if we don’t solve them we won’t see a real Digital Twin(s)
“BIM IS A STATIC APPROACH BUT WE NEED DYNAMIC ONE”
“BIM HAS DEVELOPED FOR DESKTOP AND SIMPLE SYSTEMS, IT IS NOT EFFICIENT FOR COMPLEX SYSTEMS LIKE DIGITAL TWIN(S)”
I included the answer/solution inside the content:
Keys: Dynamic + Complex
So, who can recognize the answer? Those who are in Building Performance and Building Energy area 
BIM+Simulation is the answer. “The industry needs a new schema/approach”
I talk about a live model, a real representation of reality inside the software
And to achieve this level we need to combine IFC with at least two other things (which both are from simulation territory)
So, I shared the solution with buildingSMART friends, especially to @jwouellette, @berlotti, and a little bit with @jonm
Plus @Moult which knows clearly what am I talk about
However, what am I thinking needs time, and I ensure that we will see it soon, from buildingSMART or maybe other organizations
The industry is competitive and those who plan better and act better in the long-run are the winners
