I'm not asking to modify the luatex kernel, I'm just asking for a small
lua function that everyone could use as a convenience. It would not
solve all the problems of priority, but it would make every package
maker use the same function to register their callback.

I agree. In fact I don't see the problems with ConTeXt, LaTeX, plainTeX,
etc. it would just be a function provided by a lua file distributed with
LuaTeX... I must admit I don't know the exact structure of LuaTeX, so
maybe there are problems, but if there are, can you explain them?
