I can update and say that they are actively working on this issue. I actually recently took place in a beta testing session to check out the new tools for error reporting and in fact showed them what I’ve built out (linked above) to help with real-time error reporting. The new toolset is going to be quite robust compared to what is in place now, much more intuitive to navigate, and will hopefully include a nice breadcrumb style methodology of detail levels per error.
Unfortunately I don’t have details on how long it will be before it goes live, but that’s one of those features you want to check @KyleJepson’s LinkedIn page, or even your features page within HubSpot to find out when it goes live!
One thing that I do love most about HubSpot. They honestly listen to their user’s ideas, and actually implement them as well!
