@kenjis Do we need to update all the matches in the code?

No. Services::request() returns the current Request object.
The parameter $config and $getShared are deprecated.
So if the code wants the current Request object and does not pass any parameters, it is okay.

In test code, there is no current Request object, so we need to prepare a correct request object for the test by ourselves.
