If debian adopt them probably  we can put them in texlive too --- see
patches in source/libs/luajit/TLpatches .
Lua/Luajit  is  a bit different from  libpng, harfbuzz ..., because by
design it can be modify to be adapted to the application
(while in general we modify the application to mach the library ) , and
this is what we have done with luatex & luajittex.
