I searched for information about LuaTeX in general; as I say, I didn't 
realize it wouldn't natively handle complex scripts, so I wasn't really 
looking for information on that.  And most everything I saw said how 
good Luatex was; I never ran into anything that said "Don't use Luatex 
if..." or "Luatex is good except..."

And I hasten to say that Luatex has proven good at some things, like 
getting information out that would be inaccessible in other *TeXs.  (In 
particular, information about the contents of boxes, which I needed in 
my project.)  It just had significant limitations with regard to complex 
scripts that caught me by surprise, as I had come to take them more or 
less for granted.

I'm not quite sure what you mean here.  Perhaps by "making LuaTeX use 
HarfBuzz", you mean forcing it to use only HarfBuzz.  If that's what you 
mean, no worries; as long as I could turn on its use of HarfBuzz 
(whether by command line parameter or a TeX command), that would be fine.
