And it seems that this is the number of packages written in C++:

$ repoquery --disablerepo=* --enablerepo=rawhide --source --whatrequires
'libstdc++.so.6*' | sort -u | sed -r 's/(.*)-.*-.*/\1/' | uniq | wc -l
2396

I'd like to point out at this place, that this would help also the 5006
packages written in C, since they don't need C++ to build. Only 14.8 %
of packages, which happens to be written in C++, would not benefit from
this change.
