Yes, I know there is a browserify-shim transform, but it should as easy to expose a global, as it is with b.require. For example, using subarg syntax and the same args for b.require:

"browser" : ["./angular.js", {"expose":"angular"}]

or

"browser" : {
    "angular": [ "./angular.js", {"expose":"angular"}]
}

I see the following advantages over browserify-shim:

1. Open the floodgates, it is a one-liner PR to convert many existing packages to support browserify
2. No transform = no dependency, again helpful for convincing others to add support
