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).
