Yes, I agree in general; the few problems I had were to do with the different
syntax for accessing low mem globals (which, of course, one should never
reference :-). Being able to use MPW header files is something we should
all applaud even if it means a few changes to our code now.

There was a small problem with the header files on the 7.0B4 CD; I don't
know if it has been fixed or not. Just in case it hasn't, in types.h
you should change the lines

#ifndef NULL
#define NULL 0
#endif
#define nil 0

to read

#ifndef NULL
#define NULL 0L
#endif
#define nil 0L

and rebuild the "MacHeaders" file.
