When debugging a production level application like an angular app, java microservice we often need to add breakpoints into methods which are called frequently. For an example rendering method in the frontend or event subscriber on the consumer. But most of the time we are only interested to suspend on these methods when it was triggered from a another operation which we are interested of.

How this is done in Eclipse is using trigger point, We can add a trigger point (different kind of a breakpoint) on the operation which is called before our debugging method, so once only this trigger point is hit, our rendering or event subscription breakpoint will get enabled. In IntelliJ this is done using breakpoint dependencies.

having this support for vscode would be really beneficial, if we can build this on the vscode debug extension layer, we could even support polygot scenarios, where the trigger point is in one app we are debugging and actual breakpoint which get enabled might be on another app.
