Can't speak on behalf of any EB team member, but from what I've seen with both RTRPE and EB0.8, it causes no problems whatsoever.

If you do this using the Total War: Eras or whatever it's called, you just follow step 5.
Forgot about that, but haven't really tried it anyway since this method is still pretty simple for me - I just copy my whole BI backup directory except for the BI subfolder and install mods over that, which gives the same result as the above steps. If you can give a brief run-down of what Total War: Eras is and what it does (including links) for those who don't know, it would be much appreciated.
