Recent personal experience has me doubting that I can really script a long term trust to do what I want decades down the road. Some family members did a set of trusts. Now that one is irrevocable, the surviving spouse has determined that what is doing is not what they now want. Too late. Moral -- be careful what you put into a trust. Update as needed.
I'm going to revise ours in the near future.
If your going to create an irrevocable trust... get it right the first time.
Yes, the other advantages you mention do make sense to me. But as you say, the irrevocable part is a tough pill to swallow. Tax laws change, situations change.
I know people who were being hit up to do some of this complex and irrevocable stuff that they didn't understand back in the 90's when the estate tax limits were ~ $600K and 55%. They didn't bite, and good thing, as their estates are nowhere near the current ~ $5M limits.
And even though we, nor anyone we know, are near those limits, I still think the rate should be 15%, same as LTCG. I think the 40% rate just motivates work-arounds, and people other than the other taxpayers benefit, which defeats the purpose.
