Nice! Tangentially related: I built a (MacOS only) tool called clippy to be a much better pbcopy. It was just added to homebrew core. Among other things, it auto-detects when you want files as references so they paste into GUI apps as uploads, not bytes.
clippy image.png # then paste into Slack, etc. as upload
clippy -r # copy most recent download
pasty # copy file in Finder, then paste actual file here
