On regular sites, the current community you're on lists its meta directly under it in the new Multicollider. The big exception is that there's no meta listed when you're in SE chat and not under a site, or when you're on the Stack Exchange homepage, or the full hot questions list, or anywhere else where the generic "Stack Exchange" entry pops up as the current site. Up until yesterday, there wasn't anything to list there.
But now, Stack Exchange has a Meta to list there! So, let's get it up. Yes, there's already a "meta" link in the top bar on most of those places, and I personally have MSE as a favorite site anyway, but it feels quite inconsistent not to have the meta listed right there where I always look to get to the meta of the site I'm currently on.
