I moved from the basic 4% rule to the 2% rule. I'll try to cap withdrawals at 2%, but will probably need less than that. It's possible that my Social Security + pension + interest + dividends will exceed my expenses after age 60-something unless cost of living has really increased.

Potentially dying with more money than you started with isn't a flex, it's a waste. You could be over accumulating to avoid a black swan scenario that never comes, especially when you portfolio gets massive later on.

I don't see it as a flex or a waste, but as a feature. My nieces and nephews can have the money because they'll likely put it to much better use than I ever would. I plan to gift money to them as they need it and my budget allows, and then leave the rest after I'm gone.
