New version submitted to CRAN; until then:
install.packages("rgrass7", repos="http://R-Forge.R-project.org";)
should pick up the latest version; #3425 closed. Please report back
whether this works ... (conditioning on GRASS version to create comparable
driver name strings).

Thanks for trying to contribute. The GH site is not the rgrass7
development site - that is SVN on R-forge (GH is a very preliminary trial
site for using sf vector representation in R, and maybe raster raster
representation (or forthcoming stars), instead of sp classes).
GRAS 7.2.2 works OK with the current logic checks; I can reproduce the
issue in 7.3 (latest); there is a change in vector/v.in.ogr/main.c
returning the DriverLongName for GDAL >= 2.0; in GRASS 7.2.2, there is no
such change. Could the GRASS developer responsible for this obvious
regression provide an additional flag in v.in.ogr (and v.external,
v.out.ogr) to permit backwards compatibility? See line 387, needs to
change
#if GDAL_VERSION_NUM >= 2000000
to add a !backwards_compatible test too.
I'll hold off trying to fix this in rgrass7 because it is a regression. I
can add the backwards_compatibility=TRUE flag to readVECT() once it is
exposed.

In the readVECT function, internally v.in.ogr is used to list the supported
vector format and it is compared the format available using rgdal (or sf).
However, using v.external instead of v.in.ogr fix this single problem
because of the way the output is different (in form).
For example, if you use v.in.ogr you will have to compare
SQLite_/_Spatialite
(GRASS) to SQLite (R) and they are not the same.
I tried to send a PR, let me know if it works

Hi everyone,
I think that using v.external -f (instead of v.in.ogr -f) can fix this
issue (didn't try yet)
execGRASS("v.external", flags = "f", intern = TRUE)

in a quick check, there is no difference in available formats.
