Paid support is available until May 2030:

Our current minimum GCC compiler requirement is version 8.0:
https://git.dpdk.org/dpdk/tree/doc/guides/linux_gsg/sys_reqs.rst#n32

Which GCC version is required to support -Wshadow, and which GCC =
versions are included in relevant distros?

Maybe the -Wshadow can be added conditionally, depending on compiler =
version.
Shadow variables will not be caught locally, if using an old compiler =
version. But the CI will catch them in the tests running on recent =
compiler versions.
