Rather than trying this just within R, we're hoping that the GDAL 
barn-raising effort:

https://gdalbarn.com/

will take us there and further, and be much better than having a 
non-standard implementation.

When that effort is done, we'll be open for ideas about interfacing it 
through PROJ and GDAL, which now ship with CSV files that we copy into 
Windows and MacOS binary packages (rgdal, sf, lwgeom).

For now, if it helps, rgdal::make_EPSG() reads the EPSG CSV file shipped 
with PROJ into the R workspace as a data.frame.
