Would it help the discussion if UA implementors described how they
solve these problems now?

for Gecko.
I'd be curious to hear what other UAs do.
As I suggested in one approach, for "natural" instances (in lack of a
better word) of Nodes can have all the in-memory layout optimizations
they need.
Some of these are not just optimizations; some of these are needed for
correctness. For example, we use fixed parts of the object layout to
cache values for some Web IDL properties that need to keep returning the
same thing over and over again.
