I don't see that listed on the wiki features list yet, for either current or planned features. Btrfs does have an ssd mode (enabled automatically in current kernels if non-rotating storage is detected), and a couple additional optional mount- options (ssd-spread and discard) that could be helpful on some but not all SSD hardware, so those are NOT enabled by default, and btrfs does default to allocating separate data and metadata "chunks" on demand (unless the filesystem's too small, under a gig, in which case it defaults to "mixed"), but I don't believe it's possible to tell it to put data on one device and metadata on a different one, for instance.
