“RE: MetaWeblog.getRecentPosts: Conflict and Confusion”

My advice: implement to the spec, and also implement mt.getCategoryList. (I note that you've already done mt.getCategoryList.)

http://www.movabletype.org/docs/mtmanual_programmatic.html

Here's why:

1. Any client that doesn't handle metaWeblog.getCategories according to the spec already doesn't work with Radio and Manila (and possibly others). The client has a bug that should be fixed -- but it's not your bug.

2. For many clients, if you tell them it's an MT-compatible site, they'll use mt.getCategoryList instead of metaWeblog.getCategories anyway. So the metaWeblog.getCategories method isn't necessarily all that important. (NetNewsWire 2.0's weblog editor, for instance, calls mt.getCategoryList for Conversant sites.)
