If you are using a screen reader to explore a table, finding relevant headers via the headers attribute has been an important use case for some time (as in, years). Unfortunately the more powerful and less code-heavy approaches such as the use of scope and axis attributes have not had nearly the same level of implementation, so in practical terms this attribute is important to accesibility (as in "don't break the web").
