Norman Barker is supporting it through PDAL's support venues, and I believe his firm is available for paid support opportunities. It is going to perform much better and it supports streaming. The SQLite drivers were a proof of concept that I developed based on our experience with both the Oracle and pgpointcloud drivers, and while it is interesting for database storage of point clouds, it has some significant downsides.

Numpy is also a candidate. We don't have a writers.numpy, but all the code to do so is in the Python extension. You could then save npz files and transit your data that way. Happy to merge a patch on it, but it won't make the 2.0 release cutoff.
