Maybe in the year 2050 some future intern/employee will be adding to the Office code and wonder about the "Don't touch this" code relics of the past that someone from long ago left for future generations.
I mean, in 2018, I'm scared witless of all that. Anything cached in background to someone else's computer by something as unstable and slow as ECMAScript is just... a very bad idea. Keep programs local, and don't use Web coding / scripting for anything but the Web itself through a free-standing browser.
