Right now we are also trying to figure out babylon/babel versioning. Currently babel depends on the parser so if any proposal feature needs a spec update (would be a bug fix, but also breaking) we have to major bump babylon and thus babel. I think what we are thinking of doing is making each spec update a "separate" plugin name.?

  "plugins": [
    "template-literal-revision-stage-3", // or
    "template-literal-revision-sha-git-sha-here", // or
    "template-literal-revision-sha-tc39-meeting-date-here", // or
  • is it feasible to split all plugins into separate plugins (files) like jsx/flow currently are
  • separate files per spec change means no need for a major version bump in babylon (all experimental is opt-in)
  • each babel transform would require a specific babel plugin + do a major version bump to the new plugin string

Ok current idea/solution is to go with this ^

decorators has a decorators2 now. And the new transformation will use that instead of decorators.

This allows us to do minor bumps in babylon but major bumps in the experimental proposal plugins/presets that will* change?
