That's true, but I wouldn't feel safe about it. The PHB has been out a few weeks only, and people are already complaining about a few stuff. Nothing major at all, but still stuff that is so clearly fixable (e.g. Druid's near-immunity to damage with at-will wildshape use at 20th level, Fighter's unlimited HP healing via second wind) that they will have a hard time resisting the temptations to do so, if complaints are loud enough.
One very consistent thing we've seen with 5e is they've entirely ignored the volume of complaining, and only looked at quantity. Loud voices seem meaningless to them this time around. So if 50 loud people complain about the Druid's level 20 ability, but 500 people approve of it in survey feedback, I feel safe in saying they will go with the 500.
