Note that in 61, this feature was behind the --js-flags=--harmony-number-format-to-parts command-line flag; it will be added to about:flags (as part of the "experimental JavaScript features" option) in an upcoming Canary, but is not presented that way in the current Canary.
This is a V8 feature, so I'm not sure how to use OmahaProxy to verify it directly. Here's how I verified that it was present in 61 behind that command-line flag: The current v8 version listed in OmahaProxy is 6.1.534.32 . If you open a V8 checkout and do "git log 6.1.534", then contained in that log is the commit with SHA-1 6c1e67f806d23ce23e398d3b210000349d1be267 , Change-ID I306dd1721cc00c5820b061f14c4b6866f8d938f6 which implements this feature.
