This came up here: https://github.com/r-spatial/sf/issues/2166
It seems to me that GDAL queries PROJ's ability to access the network for datum grids once, and remembers that. That means that applications can't switch this on and off on demand and expect GDAL to follow. Is this the case? If this is the case, is there a way applications can ask GDAL what this state is?
R package sf interacts with PROJ through GDAL as well as directly. This sounds messy, but some users want to get NA coordinates back for points that are not transformable.
