Efficient stack acccess is important for C, too. Putting local variables
on the stack makes functions reentrant (not so important for small
devices), and also saves memory (bery important for small devices).

The STM8 and S08 with their efficent sp-relative adressing and the Z80
with the index registers thus make better targets for C compilers than
the MCS-51 and HC08.
