I don't mind this feature to be included in Home edition. I would even just got rid of all editions and have just Windows :) Although i still believe most home users won't find this useful (i know that my parents are not afraid of anything because they just don't get that something can be harmful on the internet, even if i tell them this repeatedly, and they surely wouldn't or know how to use Sandbox), what i meant that this feature for sure should be in Pro and Enterprise versions, because that's the only version usually used at orgs/companies and i provided an example what you can use it for. Pro is used for work and checking suspicious files can be part of your work. Again, dedicated or freelancing security researchers probably would also prefer to use Pro edition to have all other advanced features along with Sandbox.
