Anthony, I'd just reiterate the value of ensuring compatibility not just with existing userscripts, but also userscripts that are compatible with other userscript addons, such as Tamper/Violent and others.
In other words, its not just the past, but also the future to consider in terms of compatibility with other userscript addons. If shims/transpilation can ensure that compatibility, my suggestion is to make it a priority for the new version. A longer-term consideration is to engage in discussion with other userscript addon authors and work towards an agreed async API. It will take longer than you probably have for the FF57 deadline, so the shim/transpilation idea I would suggest is a more immediate priority. My key point is you don't want to marginalise GM by being incompatible with others, especially when those others are already cross-browser compatible. Damo.
