 This file contains definition of resources that will be translated for each
 locale.  The variables is_win, is_macosx, is_linux, is_ios and is_posix are
 available for making strings OS specific.  Other platform defines such as
 use_titlecase are declared in build/common.gypi.
 
 The strings in this file are specific to iOS, thus is_ios will be true and
 all other OS specific variables will be false.

With the removal of the spoofing strings, is this line relevant any longer?

[Eugene But (OOO till 7-30), 2016/10/24 15:57:58]

Good catch. This was not relevant even before removing Spoofing Strings. Safe
Browsing was a separate feature which is also no longer supported.
