Not yet, I did some cursory glances and it looks like they're missing RAW support for quite a few camera(all the Sony A7* series). They also seem to have very limited lens correction profiles(missing some classics like Canon's 35mm F1.4).
I will say their UI and look & feel looks very much like lightroom although I'd be curious what their culling workflow is like.
The lens correction comes from the lensfun project, which is also open source. They even run a lens calibration service if you submit the necessary images:
A lot of distributions have ancient versions of lensfun for some reason, so upgrading can make a big difference. They're currently working on splitting the lens definition file into a separate package from the software so that it can be updated more frequently.
If you have any questions for the developers you can always jump on to #darktable on freenode IRC. darktable 2.0 has just entered feature freeze.
I think darktable should have a single click button to be able to submit a lens calibration (which might get redirected to the lensfun API). Most people are highly uncomfortable going through all the trouble.
