Making an element with a dir attribute isolated by default was indeed
considered and rejected due to backward compatibility considerations, as
explained at length in the article.

Making an element with a lang attribute have direction and/or isolation by
default is something that should be considered, but is orthogonal to our
primary aim: making directionality declaration use isolation by default,
since the lang attribute is only rarely used in bidi documents.
