I love how cPanel handles this...
Their change logs give the tracking number and description of every change that is made in a way you can cross reference
This allows me to know when an item I submitted is formally addressed
Currently we have no formal way and have to hope an ST employee marks one of the possible many related posts as completed, etc
As ST is focused on using their tools the way these are handled will only get better as their products suite/tools get better and thats if they deem enriching them for bug reporting is worth it.
It's been mentioned they have an internal tool for tracking things but none of that sees the light of day.
