To institutional users: heads up! PROJ 6+ is impacting your work!

I have received scant input (no input) on my warnings and requests for
input on:

https://stat.ethz.ch/pipermail/r-sig-geo/2019-November/027801.html

Please review that carefully, and in addition please take time now, that
is best within one week (things are moving very fast), to review and
comment on the PROJ list on the draft RFC 4:

https://github.com/rouault/PROJ/blob/rfc4_remote_and_geotiff_grid/docs/source/community/rfc/rfc-4.rst

(threads:)
https://lists.osgeo.org/pipermail/proj/2019-November/009021.html
https://lists.osgeo.org/pipermail/proj/2019-November/009024.html
https://lists.osgeo.org/pipermail/proj/2019-November/009030.html

This concerns conditionally permitting PROJ (so here rgdal, sf and lwgeom)
to download granular subsets of transformation grids behind the scenes to
a user-writable directory, and then use these in coordinate
transformation. The download would be from "the cloud", a content
distribution network.

In practice, this would mean that platforms connected to the internet, and
after approving access to the CDN, would start "grabbing" grid portions
from the CDN and using these for transformation, rather than say using
institutionally sanctioned grids. The CDN grids are expected to be best of
breed going forward, protecting us forever from horizontal and vertical
shifts and giving full geodetic accuracy wherever applied (and where
national mapping agencies agree to publish their best grids).

It would be best if several list members at institutions with R-spatial
workflow components or with relevant experience discuss this rapidly
off-list (contact each other on list to volunteer if need be), respond to
the PROJ list about the RFC draft before it is completed, and report back
in this thread. Nobody will be able to help later if you sit on your hands
now, now is when your needs can be protected for the next decade. For an
individual academic like me to respond on your behalf would be most
inadequate, as I can only speak from experience in individual research and
teaching settings.

Please take action urgently, this is an opportunity to contribute to
shaping critical shared infrastructure with ramifications way beyond
R-spatial. Please also offer me the comfort (offlist) of knowing that you
are going to respond to the PROJ list request for comments on the RFC
draft, it feels very lonely here trying to guess what your needs are.
