@nowosad Thanks! This is a heads-up, really, but if some of us can talk in Warsaw at useR! - if it is actually a concern - that would be a useful opportunity. I've drafted an abstract on the repo: any comments welcome on https://github.com/rsbivand/new_ref_systems

@rsbivand @nowosad I don't know R, but if I can help with the NSRS part, let me know.

@rsbivand @nowosad If you think this is similar to what may happen with the modernized NSRS, they are very different situations. The changes in EPSG regarding ETRS89 are changing current systems and transformations. The modernized NSRS is a completely new set of systems and transformations. It will be challenging, but a different thing.

@jjimenezshaw @nowosad Yes, they are different, but as they are happening in the same time period, users will also need to understand the differences in the changes they are facing.
