The longer GCC compilers are being shipped with the old behaviour, the more code will be broken, or not? With GCC10 being in common distributions like Debian stable, we are actively contributing to the old definition being around... Since views were introduced in GCC10 (and are not an old and established feature), I think that the situation here is different from for other "breaking changes" and that we should quickly try to homogenize the GCC behaviour for as many people as possible. I think that was also the reasoning for "allowing" the change in the IS. [Note that I was not strongly in favour of this change, I am just scared of writing code that might change behaviour unknowingly soon ]
