I'm in the under 50 group with a modest RHA so far and still love the idea of shoving as much as I can into a CBP for over a decade plus hitting 415c limit plus catchups in your 50s plus backdoor Roth IRA before rolling it over at 59.5. Doing the math on that it's an opportunity to stash an astonishing amount in a relatively short period. But I also don't think it will pass and understand it could use a few tweaks for many.
