With a maintenance cost. But yes, it could be done.

It would also fix anyone who has compiled Frameworks with ASAN and
needs to use a build system from elsewhere which does not use ECM
(Such as QMake for instance, although why you'd use ASAN in Frameworks
and not your app is another thing altogether of course)
