Apparently Epson has abandoned Image Scan v3 in favor of Epson Scan 2

It looks like Epson has abandoned Image Scan v3 in favor of Epson Scan 2 (AUR package: epsonscan2):

Also, note that utsushi/imagescan, which .nvchecker.toml checks against, has been archived - it tracked upstream releases, but was archived since Epson no longer updates Image Scan v3 (and Epson Download Center no longer returns Image Scan v3 in search results).

While utsushi/utsushi hosts a community version of the software, commit history shows that it is not actively developed.
