Of course. Yes, the key motivation is really coming from Node. We (IBM) want to be able to produce localized outputs such as help, debug and error messages in a reasonable way but there are a handful of errors produced by V8 that are not intercepted by Node (For instance, when someone attempts to modify a frozen object). We do not want to end up with a situation where only some of the messages are localized and others are not so I'm attempting to figure out a workable path. And yes, the goal is to produce localized outputs for non-English speaking developers (done in a way that is still "search friendly" so that developers can easily look up details and documentation for any specific error).
Within node core itself, assuming this capability lands, the default would be for non-localized outputs. Vendors (such as IBM) who build on top of Node would have the ability to generate localized-but-still-fully-compatible binaries. We (like many companies) have specific obligations to provide localized versions of the software we provide and Node currently requires an exception process for us since a localized version is not currently possible.
