Is it a problem? I wouldn't call it an earth-shattering one, but yeah, I think we're rife with opportunity to, say, take a note from Docker's use of UnionFS, to provide common baseline electron, and layer on dependencies on top of it.

For first world countries, the concept of burning gigabytes of data on the daily is no real concern, but in less connected places, less privileged regions of the world, gigabytes an hour is a pipe dream. Even for us folks with more dense data connectivity, making more room on transit bandwidth is a boon for everyone (even if it is to make more room to stream more cat videos).

Happily cede that it's not a top level concern, but I do agree with the sentiment that we can do better, and we should try to.
