Using HTTP_Request2 in Services_Akismet

Hello, I am the developer of Services_Akismet. When HTTP_Request2 was released, a feature request to use it in Services_Akismet was opened [1]. As excited as I am about using it in Services_Akismet, there is a bit of a problem. Services_Akismet is a stable package and using HTTP_Request2 would necessitate changing the API (presumably for the better). Because Services_Akismet already contains a poor-man's implementation of HTTP_Request2, I have a few options: 1.) Break BC, but only for people who bothered to use HTTP backend abstraction in the current stable package. 2.) Add HTTP_Request2 as a backend to Services_Akismet's HTTP abstraction. 3.) Release Services_Akismet2 with a slightly cleaned-up API and remove the duplicated HTTP code. Of the three, I'd really hate to do #2 as I don't feel HTTP abstraction belongs in Services_Akismet anymore. For either #1 or #3 I already have the code completed. I'm looking for opinions from the PEAR community as to which approach is best. Season's greetings, Mike [1] http://pear.php.net/bugs/bug.php?id=15069
