Is it that hard to provide a proper for-loop where you don't have
to spell out every single detail?

You mean like in Algol 68 or maybe Simula? (Both are interesting.)
 

 
I mean like pretty much every language that hasn't copied C's
for-loop syntax. For example Lua:
 
   for i = a, b                  # iterate over a..b inclusive
     s1
     s2
     ...
   end 

 
Obviously there are many and there were many programming languages
that have other and better loop syntaxes than Fortran or Lua (if
above code is all that it provides).
 

Modern Fortran do construct does not lack in features.
There are languages that match it, but it's hard to see how one can
improve on it without impacting one or another usability aspects.
