HttpComponents would be SFL4j in my structure. They definitely need debugging.
Lang or Codec don't. If I had to generalize, I'd say it's because HttpComponents is not at the bottom of its stack. You need to know what the communication is between HttpComponents and the API below it (ie) a http connection to a server). Digester and DBCP are two other areas in which logging is very attractive (how is it talking to the XML or a DB). Pool less so imo - what you really want is status information on the state of the pool. Ideally we're talking event-based systems and querying rather than just simple logging [not that I've looked at Pool in eons]. It's a set of decisions you have to make - what I'm advocating (with 'if you can help it') is to ask yourself "do I need logging?" rather than "how can I add logging?". I think a lot is added due to the latter approach.
