No. We went through this already. Programs might need different
initialization values and the value the kernel/libc uses might also
change. I son't want to encode anywhere a value which would tie a
glibc version to a specific kernel version. The patch is minimal,
introduces almost no costs and it helps in every situation to determine
whether the default behaviour is the one wanted.
