Although optimizers are a valid subset of players, I think they're a pretty small minority. Given the overwhelmingly positive reaction to monks, I don't see nerfing them because of fears that wizards or sorcerers will take a 2 level dip. I also don't think it would be that great. Yes, they can take the dodge action plus an unarmed strike bonus action at level 1 (so 6.5 average damage on a hit); that doesn't seem gamebreaking. A two level dip would allow a wizard, say, to take dodge/disengage as a bonus action twice before running out of discipline points; again, that doesn't seem gamebreaking.
The point that you can dodge and attack resource free all the way from level 1-20 is true but not that great. If you are doing it resource free, all you are getting is dodge plus one unarmed strike, even at level 20 (average 11.5 damage at level 20). Which I think we can agree is not exactly terrifying.
Stunning strike got nerfed to one attempt/turn in the UA, which I think was needed. The ability I think is actually overturned is deflect attack; since reactions are generally wasted this becomes almost a free, powerful damage reduction.
I very much disagree that monks are currently fine! Player consensus on the monk class has been very clear since 2014.
