One of the (non-accessibility related) reasons for wanting this is that Basis uses this attribute to change the tablesort indicators: https://github.com/backdrop/backdrop/blob/f3fa59b6cb8cb15e06e0ccf040fd5bd6a48d9690/core/themes/basis/css/base.css#L179

In the case of Views' tables, Basis is forced to use the default tablesort indicators, causing a break in the consistency of the theme's design.
