No, this is very much a proj and packaging thing. We just call the API.
As modern proj got better at grid shifts and finding the best transform chains,
the proj team started collecting more grids. Eventually the grid collection got
so large that distributing it as one unitary package stopped seeming
reasonable. So network/cdn access was adopted, but as a result a "bare"
distribution now includes zero grids, whereas before it was common for a
packaged proj to at least include grids for the "more common" transforms.
