Browser caches are extremely unreliable and pretty small in the grand scheme of things. On some mobile platforms the browser cache can be replaced entirely by some heavy pages! Plus, even if we assumed "cached forever" actually worked for a significant amount of time, it still doesn't solve the problem that I am hoping to solve. I know many websites use the Roboto font. By installing it I no longer need to ever download that font again. It doesn't matter if it's the first time i'm seeing the site, if they use a CDN, if they link to the bold/light/regular version or their own packed font, etc... I understand that it's a privacy issue, but I'm hoping there is a way to solve that privacy issue without removing that feature.
