I agree that defining fallbacks for each font family is inconvenient. 
Defining font per script resembles specifying fonts per language in 
babel configuration, however fallback should work without explicit 
switching of language. I have seen that babel may determine language 
from character code points, but I have not tried if it works reliable 
and if it affects performance (as it does for fallback fonts).

Maybe I did not read the manual with enough attention, maybe I tried it 
with too old version of LuaTeX, but I had a problem with Emoji. 
Depending on font such symbols either broke compilation or did not 
appear in PDF (accordingly to pdffonts font was embedded, text may be 
copied, but PDF viewers displayed blank space).
