Is not the same. With this service you do not need to have anything installed in both the sender and the receiver. So you can use it to move files to a server, send a link to a friend who does not know how to use a terminal. Very practical

Think they did a great job but I think they are pointing to a slightly more general public leaving out developers, musicians where they use plenty of peripherals working in parallel without being dependent on a multipurpose adapter which by the large amount of workload this has little duration of life for the multiple use is given much is to connect power, monitor, external sound plate, mechanical keyboard, etc ... all this to make it flatter slopes of implementing the USB-C

Not everyone wants that your browser interpret everything by default and other causes over which you mention, that's why I put aside that idea to include them by default in the future maybe there is something similar in browsers.
For my part would be better to make an addon that includes the libraries and spread it for users who want this to install on your browser.
