Currently the core library is closed to new language submissions as there are not really even enough core maintainers to maintain our existing languages (much less add and support new ones).

Context: #2149

We'd be happy to create a repository for you in the highlightjs organization if you'd like to host (and maintain) your grammar there. And feel free to join the discussion.

I'd like to make it much easier for people to build custom bundles (including 3rd party grammars), that is something I'll be looking into after we switch to a simpler build system for the core library.

That said it's currently terribly easy to "add" a new language just be including an extra JS file in the browser... so if vlang.io wants to support this they only need to include the vlang.js file AFTER they load the main library, or build a custom build.
