  # `enable_desktop_android_extensions` is an experimental flag used in
  # prototypes of desktop-focused android-powered builds. This is very much
  # in-development, non-stable, and likely to crash at any given moment.
  #
  # Introducing a separate flag like this has the unfortunate effect of leading
  # to a lot of `if BUILDFLAG(ENABLE_EXTENSIONS)` checks in extensions code
  # itself, since those checks are instead the equivalent of
  # `if BUILDFLAG(ENABLE_FULL_EXTENSIONS_SYSTEM)`. However, we don't want to
  # change the stable, production-utilized `enable_extensions` flag for this
  # experimental build.
  #
  # As the experimental build progresses, there should be fewer of those
  # checks littered around the extensions codebase, since more and more of
  # the extensions code will be included in the desktop android variant.

  # TODO(https://crbug.com/356905053): Continue expanding the scope of
  # enable_desktop_android_extensions.
