after quickly testing on linux (didnt test windows), games run fine, but you need to launch them through minimal mode and you won't be able to chat with people (and you will be offline), because that is handled by the now disabled steamwebhelper. also updates might revert these changes, but that shall be seen
FYI this doesn't seem to work anymore with the new Steam client update. seems like they removed basically all of the old non-webhelper interface
