Well... somewhat. FWIW I was present at q66's talk at the lua workshop last year (https://www.youtube.com/watch?v=J_hlbjj_9-Q). From what I recall it was more of a full application framework rather than a library usable from existing processes.

I did try to give them a go at some point, but could never get things working.

Aside from this, the reliance on luajit makes this a no-go for me. (though perhaps you can use luaffi (https://github.com/facebook/luaffifb) to alleviate this?)
