We'd like to think so... but it wasn't so long ago we had dozens upon dozens of threads here on the boards decrying the arrival of the 4E "Expertise" feats because now they no longer had "any choice" in feat selection. They were taking that feat because it was objectively better and thus they felt like they no longer had any opportunity to take "interesting" feats. Their egos wouldn't allow them to forsake the objectively better choice for the more interesting choice.
And with +1s as a substitute for feats... I do think (as I mentioned above) that unless these new feats are tremendous... four out of every five players will take the +1s until they reach 20 in their prime stat. I just think that's a fait accompli.
That was true for 4e because AC scaled with level and in order to be better at hitting level appropriate monsters a player felt compelled to gain more "to hit" bonus. With 5e, even at 15th level, we may be attacking a beast that has AC 12, 13, 14; therefore, there won't be as much pressure to make your +7 to hit a +8.
And from what Mearls is implying, the new feats will be tremendous relative to the older feats.
