To answer the OP, clarity is not necessary for that style, but you may want a longer fermentation time on such a big beer. I would give it at least 3 weeks in primary, personally. Clarity will not hurt the beer, though.
I sometimes use secondaries as bright tanks when I know my keg will get moved around a bunch and I want to harvest the yeast from primary. When I do this, I crash to 30F, then rack into secondary and add some kind of fining agent like gelatin or isinglass, then I wait a few days before racking - that gives me crystal clear beer from the very first pint.
