Is there a Lighter version of the Membership plugin?

I am looking for a way to simply limit access to certain menus and pages by role. I am using the civiCRM plugin on one of my sites, which is providing all of the Membership and Role information (among other things), but it doesn't support Members-only pages. I can get that functionality with Membership, of course, but it's also loading lots and lots of functionality that either duplicates stuff I already have in civiCRM, or functionality I just don't need.

I was looking at the "Power Menus" plugin at WordPress as an alternative, but I am leery about using free and lightly-supported plugins from a security perspective.

Is there a way to "dumb-down" Membership to just get the functionality I want?
