For others like me that didn't know the term Sherlock:

It means "To obsolete a unique feature in third-party software by introducing a similar or identical feature to the OS or a first-party program/app." The term stems from Apple's 2002 release of Sherlock 3, which made a popular third-party app named "Watson" irrelevant.
