> Just to be cautious: Is it a valid question to ask after all? We have hundreds of gigabytes of storage, if not some terabytes, and people should be using decent ISPs nowadays, so the binary size should not be a concern, right?

Phones? IoT? Embedded? OS devs? Someone just checked in a 14KB binary size reduction to our shell (by removing unnecessarily virtual methods in some C++) that was widely celebrated.

Also, smaller .dll's load faster from disk.
