I just compiled "zed" with "cargo build --release" and not only did it pull >2000 dependencies, its size (executable file) is literally 1.4G. Debug is 1.2G.

  $ pwd
  /tmp/zed/target/release
  $ ls -lh ./zed

Summary:

  $ du -h ./target/debug/deps/
  20G     ./target/debug/deps/
  $ du -h ./target/release/deps/
  8.0G    ./target/release/deps/

  $ du -h ./target/debug/zed
  1.2G    ./target/debug/zed
  $ du -h ./target/release/zed
  1.4G    ./target/release/zed

This is on a whole new level of bloat; both with regarding to dependencies AND the resulting executable file(s) (EDIT: executable files are unstripped).

Any explanations as to why "cargo" does not seem to re-use libraries (dependencies) in a shared directory, or why it needs >2000 dependencies (that I see being downloaded and compiled), or why the executable file of the release mode is 1.4G unstripped while of the debug one it is less?
