Any interest in detailed GC traces

[safety0ff via Digitalmars-d]

I found this link on reddit: 
http://dave.cheney.net/2014/07/11/visualising-the-go-garbage-collector 
and I was wondering if there was interest in having D's GC output 
detailed trace information.

I was thinking perhaps collecting data and then writing it as a 
json file when the process exits.

Thoughts?
