./pants options --cache-read-from=['<http://www.google.com|www.google.com>'] |grep read_from
cache.read_from = ['/home/ahmed/repo/.cache'] (from HARDCODED)
cache.options.read_from = ['<http://www.google.com|www.google.com>'] (from FLAG)

Is the option cache.options.read_from suppresses cache.read_from option?
