There are many users/companies using older versions of compilers,
kernels and everything. GCC <= 4.9 will still be used/supported (by
third parties) for a handful of years at least.

However, the important question is whether those users/companies care
about running the latest kernels. Many of those definitely do not want
to touch their kernel either. For those that do, there are several
longterms to pick from that still support 4.9, as well as other

Thus I am usually in favor of raising the minimum whenever new hacks
are required to be added. On the other hand, we already raised the
version twice this year and it is not clear to me what is the minimum
version we would need to go for to ensure this does not bite us.

That would be better if it can be done, yes.
