IMHO point clouds are special form of vector data. But still, an OGR
driver would not be a viable solution.
... or as already mentioned of rasters (or grids as I prefer to call
them when they are so).
By accident I found that that grids stored as XYZ in laszip are 3 times
smaller than the same grid in netCDF with a deflation level of 9 (the
maximum).
That makes it a REALLY interesting grid storage format.

Did you have a look at PDAL (http://www.pointcloud.org/)? It is
similar to GDAL and seems to have a built-in driver for LAS files.

Would there be any particular reason for not supporting it?
Point cloud is not a vector, not a raster either? :-)
That might be debatable, but it won't be me reopening that
discussion. Having said that, if you could assure me that all
formats supported in http://www.gdal.org/ogr/ogr_formats.html are
vector formats, I would have understood your point (of not
offering a LAS driver).
Rui,
I intentionally put question mark to indicate it's open question
for me as well. The nature of LiDAR data might be confusing and I'm
interested to learn more about it. Dale Lutz said, "point cloud is
a badly behaved raster". I (used to) say, it's not a vector. But I
still haven't found clear answer "what is it" really :)
