Google rolls out updates all the freaking time. Not all major ones, but they do about 800-1000 updates to the algorithm yearly with major announced updates rolling about about 5-6 times a year, if not more.

If they are going to sit on their hands every time an update rolls out, they are going to have a lot of idle time.

That being said, if your site was significantly negatively impacted by an update, it’s not unusual or unreasonable to wait a few weeks to see if things rollback (they often do) rather than just starting to tear everything down and make major changes.
