we need to make a difference between the 'event building' and the 'sending' so I made this more explicit.

Just curious, is this something that will be merged soon?

We've tried out Spotlight, but with this bug it's also caused all dev events to flow from developer machines to Sentry, with no easy way to turn it off.

Would be great for us if this could be merged!
