I know for sure about whitespace. We have some tests for interpreter,
but this has never been tested thoughtfully for the use cases like yours.
Should be mostly fine though, except some edge cases that you can report
as bugs. The original aim of `org-element-interpret-data' is creating
equivalence between the parse tree and the buffer text.

Yes, it is invalid.  You must always have :level.
You might try https://github.com/ndwarshuis/org-ml, though I plan some
breaking changes affecting org-ml soon.
