If the dialogue wheel ever gave me such a choice, I would certainly take the opportunity to shout "Marry me, you prudent fool!" if only to see how Kaidan would react. 
Does Shepard have better things to be thinking about? Certainly. But there's bound to be "When this is all over, what happens to us?" moments. Liaramancers got to have a line about "little blue children," so I would love to see future-planning conversations like that for the other romances. Especially Kaidan. He's such a sweetheart that I bet he would just melt over the idea of wedded bliss with Shepard.
Yet again, I find myself totally agreeing with you. Whether it's an event we see in-game, or in an epilogue, or simply something Kaidan and Shepard end up planning to do "when all this is over, if we survive," I'd adore the option.
Just an option - I know a lot of people are opposed to it, but they wouldn't have to choose it. For my own part, I would just melt.
