The wear and tear issue is a big one at a couple of courses I've played quite a bit which have stopped overseeding. Where cart culture is dominant and money is available, I think overseeding will become the rule again.
Another twist is on the overseeding of hybrid bermuda greens. Apparently, the rye or poa/bent seeds have a hard time penetrating the new hybrid canopies, making the overseeding lighter and spotty. Aesthetically and performance-wise, the results are not what are expected and some courses have skipped this process. Instead, they lightly sand the greens periodically and sometimes apply dye/paint. The benefits and detriments are the same. I have actually putted on greens that are at their best when dormant (smooth, little grain), and others that become mushy, bumpy, and muddy in places.
The good thing about bermuda is that if it gets enough moisture throughout the year, when it gets sunny and hot, it seems to come right back. There are probably some diseases which it is susceptible to, but for years I couldn't get rid of the stuff in my flower and shrub beds even with Round-Up.
