Integrations object should be respected, aka Selecting Destinations

[WesleyDRobinson]

Selecting Destinations (in analytics.js docs, it was recently renamed to: managing-data-flow-with-the-integrations-object 🙄 in analytics.js)

Referenced in common but not really used:

functions-library/buildpack/boreal/window.js

Line 185 in 762398f

setAttribute(res, "integrations", d.integrations)

I would like to send events like so:

Segment.track({ 
  // userId, event, properties,
  integrations: { Salesforce: true },
})

Currently, we have to set "Always Enabled" in those specific Destination Settings, and that is a bit precarious!
