Review Comment:
   The <p> note above the method already routes callers to the overload that 
takes the lengths. I left @Deprecated off because it commits core to removing 
the method in a named release, which is a committer's call rather than 
something to fold into a bug fix - #15470's tag was set by that PR's author for 
their own method. Happy to add it if a committer wants it here.
