My knowledge about handlebars template and our integration of them is a bit
rusty, but are we sure that above does not allow code injection that can
alter the UI in some odd way, less an issue for users but might allow easily
to replace our product trademarks and other barriers that ensure that our
product stay economically viable without having to modify the code?
