Thank you for the updated tables.
I am also a bit confused about the PGI/NVIDIA compiler (2008 table contains PGI 18.1, 2018 table has Nvidia 16.4 instead), could you clarify that? I would expect here a recent version (22.x) of nvfortran.
Regarding the outdated data, maybe it would be easier to collect information if the browsable database discussed in Compiler support tables was implemented? In the end, we want to increase vendor engagement in the adoption of new language features, maybe this could become a PR thing where we use vendor inputs to rank compilers?
