I sincerely would prefer not to pull C++ in. It is not just a matter of 
"speed" but also of trouble. As well as of sheer "installed size". The 
C++ part is the most troublesome and unportable. in GCC for example, 
using it on different platforms, it is most often easy to upgrade C and 
Obj-C to a newer version, but it is always C++ giving issues, both with 
headers as well as link time.

I am very proud that you can build ALL GNUstep parts I use except one 
single component without C++, it is very easy on certain installation 
and the choice I did on Raspberry, for example (even if there C++ 
works). The only component which needs C++ currently is PDFKit because 
of xpdf. Obj-C++ is not needed because of a wrapper.
