Finally got around to hooking up EditorConfig into my Vim setup…
" Look for and interpret .editorconfig files.
" https://editorconfig.org/
packadd! editorconfig
" Use .editorconfig for new, empty files.
let g:EditorConfig_enable_for_new_buf = 1
" Turn on plugin log messages.
"let g:EditorConfig_verbose = 1
The plugin is bundled as of Vim 9.0.1799.
