Selling 4m house post NAR settlement

Curious to get a pulse check on what everybody is seeing happen for the high end real estate market after the settlement.

Technically speaking, you can no longer list commission on MLS. However, my realtor tells me this is irrelevant because they will simply call him and ask what it is anyway.

Secondly, the settlement says that buyers must have an agreement in place with the buyers broker. Apparently it is still expected that the seller offers all of that commission or the buyer will merely adjust the offer to reflect any delta.

More importantly though: are most buyers in fact locking in similar large rates as before? (2-3%), or are folks more heavily negotiating, or potentially doing flat fees?

Why it matters: My agent is pushing for me to offer 2.5% to the buyers broker. This implies most buyers agreements are 2.5%-3%, however I'd assume that most folks buying in the high end range is often going to negotiate closer to 1.5%-2% -- if true, I should only offer the latter amount.
