The main reason that this is allowed is because GDAL already supports
it, in that GDAL comes with the necessary code to load libgdal
dynamically and access it through function pointers.
Other than that, it can help to work around the problems which result
from GDAL being written in C++, namely very specific library
dependencies, which typically result in a given binary only working on
a very specific platform.
