I am working on disabling /deep/ (and removing ::shadow) for M60.
See https://codereview.chromium.org/2778983006
However, it turned out that there are not-a-few tests which still use /deep/ (or ::shadow). I am afraid that the CL would be bigger and bigger, and it would be difficult to land the CL as one giant CL.
Instead of landing all changes together, it would be better to remove or rewrite tests incrementally, as separated CLs from the main CL.
After that, we can land the main CL, which actually disable /deep/ (and remove ::shadow), hopefully.
If it would take some time to rewrite some tests, I am afraid that we have to disable some of tests so that we can fix or rewrite tests later.
