Basically it's this:

Now obviously Google has a bit of an advantage here what with Chrome being their own tech but there are so many blogs out there with people talking about complicated Docker solutions just to run headless Chrome in the cloud.

It would be great if we could get a solution where we could run Puppeteer in much the same way, or allow web apps to run Chrome without having to be inside Docker and we could manage a pool of Chromes without having to manage Docker as well.
