Rather then the events depicted in Enterprise changing the universe of TOS and TNG, it might be more likely that the events of Enterprise would be erased, preserving the timeline of TOS and TNG. The Temporal Cold War was depicted as occurring on several fronts. The 22nd century was far minor compared to the 31st century. What Archer does likely strengthens the position of the Federation in the 31st century (certainly by guaranteeing its existence). Nonetheless, victory in the conflict would have to be seen from the perspective of the Federation in 31st century, and presumably, it would attempt to restore as much of the timeline as possible when it can. At the very least, the shape of the 23rd and 24th centuries would reflect more the events of the 31st century that the 22nd.
Possible consequence: we can blame Daniels for Orci and Abrams.
