Yes I would.i doubt many would do the same, lets say the company who offers the swap service goes bust in the future? or their future mobo's are not as well equipped or overpriced or poor value for money in the future, you would still choose them over their competitors due to their rma service being fast?
i will always choose the best option for me, in spite of a little mobo mishap, which they are going to sort out free of charge, personally i am seeing this as a free upgrade, i get a newer and better mobo with a longer warranty, bring it on.
Support IS a feature, and it's one I value highly.
BTW it's not free since personally I don't value my time at nothing, plus there is an inherent cost to losing access to my PC when it isn't convenient for me.
