It isn't. Apparently, there're a lot of geoscientific data sets
(SRTM- and ASTER-derived digital elevation models, some of the
MODIS datasets, Landsat imagery is what comes to mind) which are
referenced to UTM, sinusoidal or other projections. To me, it
looks like that the only field where WGS-84 is predominant in
geoscience is climatology.
Yet, as the computing power rises, and allows for even finer
resolutions to be used for world-scale climatic models, the
community is forced to look... for other ways to construct the
modelling grids, which effectively means -- coordinate systems.

Just to clarify: while the stated purpose of the proposal is to
``provide a protocol independent, compact and generic way to
refer to a physical geographic location'', don't you assume a
rather specific protocol here? Namely, one with a user seeing
an URI within his or her WWW browser window?

I don't think that most of the Internet users of today seen an
RCPT command, either. Nevertheless, SMTP keeps going.
