As always, it is a tradeoff. We have already removed gcc 4.8 (released
March 2013) even though older bootloader/kernels tend to break when
built with "too new" gcc versions.

I don't recall the same level of breakage when moving to newer glibc
versions. Is there any reason to stay with 2.17 instead of newer
version (incompatibility/bloat/..)? 2.17 presumably is also missing a
number of security fixes and nice new features.

I suggest we stop caring about these ancient <= 2.17 glibc versions when
we introduce 2.26, especially if upstream doesn't want these fixes any
more.
