It is a metaphysical statement about whether metaphysics is important in this instant, rather than being dispensed with in favor of something useful. It's picking a particular metaphysics rather than being bogged down in the meta-metaphysical question of the necessity of metaphysics.

Or at least, that's the way I read it. The question of the value of metaphysics is an open one, which easily comes to dominate other questions if allowed to. I think the OP is saying, "I'm going to make a metaphysical commitment, and let other people worry about whether doing so is good metaphysics." (And there's good reason to think that it isn't -- but it's unclear whether that matters, or should matter.)
