Newly created WAGC archive is available at https://wagc.go.art.pl/
It contains all tables, individual and country stats, and over 1800 game records.
Similar archive about KPMC (Korea Prime Minister Cup) is at https://kpmc.go.art.pl/ (without game records for now, I will start adding them later)
If you have games from WAGC (sgf, screen of kifu, any source/format) that I am missing, please contact me.
