Primary difference is that the default compiler used to compile the
sources is c vs c++.

[So, if the user is developing with c++, its easiest to build PETSc
with c++, and use the default makefiles to compile user code aswell]

There are some components of PETSc [sieve] that are coded in c++, and
can be built only in the c++ mode.
