Thanks. I'm asking around to find out whether NumberFormat is going to pull in undesired internationalization data (currency formats, mainly). I'll report back here.

The feedback I got:

• NumberFormat may pull in code that apps don't want.
• NumberFormat might not be supported by j2cl.

But I also heard an alternative approach that uses JsInterop. I'm trying that now.
