In addition to Bug 1483971 and 1483968 we would like to be able to target snippet users based on their Chrome/non-AS behaviors, i.e. clicking 'View List' via the awesome bar 'Save to Pocket' button. Again, per Tim, he thinks this covered by existing Unified Telemetry probes in the awesome bar. Per a previous convo I had with Kate, a thing to note: she was saying we can't cross-reference against AS/telemetry data on a per user basis right now. Can do MAU/WAU/DAU within snippets but not across AS or UITour. Please let us know if this will be possible and/or what else you may need on this ask. Thank you!

I'm doing some Snippets 2018Q4 goals housekeeping, related to this bug. Could you update us on the status: Will this get implemented in 64? If not, should we expect it in 65?

This will not be in 64, and has not currently been prioritized for 65, so unless something changes, will not be in 65 either.
