I think independently from what we do in 5.3 we will have
incompatibilities between versions here which can't be worked-around in
userland (I don't consider if (version_compare(...)) { class ... } else
{ class ... } a proper workaround)

So here are three choices:
- The DOMDoument typehint is certainly wrong. 
- Adding an interface is lots of additional trouble (user code will
  break again, no proper way for users to be 5.2 and 5.3 compatible)
- No typehint, as it is now, #47206 "Expected / to be documented",
  incompatible with 5.2.6-5.2.8 but compatible with most other 5.2
  versions

After reading this thread and some limited private discussion I think
the last option is the best.
