In my opinion, in a word, yes.
72(t) and Roth conversions from your 401/403/SEP plans in ER when in the ~0-10% tax bracket(s) make a lot of sense to me.
However you are in the 15% tax bracket, so you aren't giving up a ton. Well a bit more perhaps depending on the state tax situation I suppose.
15% vs 10% or 0% isn't the biggest thing in the world to worry about I suppose. Not a huge delta there.
But one thing to throw out there is that long term cap gains rate may return more to the historical norm, making your taxable investments less attractive at some point. But really, who knows. Some of your money invariably [IMO] needs to be available post 59.5 or thereabouts so unless you plan on dieing [knock on wood] before then, it's probably perfectly sensible to have SOMETHING in tax deferred space.
