This is a precursor to https://crrev.com/c/1053338 which introduces base::CheckedObserver. Existing observers will be unchecked (as they are already). There is no behavior change with this CL. The CL is mechanical. The bulk was done with variations on a sed script: git grep -l ' base::ObserverList<.*> .*;' -- '*.cc' '*.h' '*.mm' | \ xargs -IX sed -i -r 's/(^[ ]*)base::ObserverList<([^>]*)> (.*);/'\ '\1base::ObserverList<\2>::Unchecked \3;/' X With some manual follow-ups to get special cases.
