this is not a question for this list as it's also macro package
dependent; best ask this on a luaotfload related list (or wait for an
answer on se)

you can hook in code that does such things but for sure it will break
something if you use the same font otherwise; there is nothing to gain
anyway as loading a cached table is pretty fast (esp compared to other
things done in an average document); also, these tables are already
optimized quite well

this is macro package specific and as the latex loader is modelled after
xetex i suppose something is provided (context doesn't do it that way)

you probably need to use some kind of plug in system that your macro
package provides
