[Twisted-Python] Etiquette of tagging people for reviews?

Every project seems to have its own norms around this. When I have some code in a reviewable state, I will sometimes look for someone who has recently worked on that piece of code or similar features and request a review from them, just to get the ball rolling. Is this a reasonable thing to do with Twisted? Or should I just let people check the review queue when they have time for reviewing?
