A future glibc could distribute under the terms of LGPL4+, but a future glibc could NOT change the license to "LGPL4+". I.e. if LGPL2.1 had a problem, we could not fix the problem by preventing LGPL2.1 from being used. *We* could use LGPL4, but we can't take away someone else's right to use LGPL2.1. Only the copyright owner(s) can do that.
