This should be pretty straight forward without special support. Do the embedding and create a function that returns the fs.FS with your files in it. Put that in a file with a build tag or something, // +build !dev and then put the same function that returns an fs.FS that points at the filesystem in another file and add the build tag // +build dev or something along those lines. Now you can do go build -tags dev to get the filesystem versions, or build normally to get the "release" version where it's embedded.
