What other issues?

I.e. what would be lost by making the choise between a "text/html
document" vs "non-text/html document" be chosen at construction time?

One thing that seems unfortunate with the current API is that you can
call .open() on a document dynamically, thus changing behavior of any
node which has that node as ownerDocument (note that while nodes are
removed from the document when .open() is called, they don't change
ownerDocument).
