Certainly copyleft has a place, but changing the license to LGPLv3 would allow this very useful library to be used much more broadly while continuing to require that improvements to the shared code be made public. If glibc were GPLv3 rather than LGPLv3 (same goes for Boost, etc.) almost no one would use it. IMO this library will either be re-written under a less restrictive license by some other author (wasting time and effort of the community) or migrate to a more open license (LGPL, ASLv2, MPLv2, MIT, etc.).
