That's actually false. We have Linux distributions that do regularly test. I think deprecation is warranted and possibly support for some arch can be moved from best-effort to minimal (e.g. i386), but removal of all 32-bit support is not something I am in favor of. Architectural diversity in terms of test coverage improves the real-world portability, so having Debian builds run tests on s390x or our CI on armel is beneficial for robustness of the code-base.
