stack -full truncates arguments as [...]

When using bt or stack with -full, I expect to see every argument that gets passed around.
Snippet of the stack trace:

Where it says ip = net.IP len: 4, cap 4, [...] the value is truncated with an ellipsis; why?? What's the point of tracing the stack if I can't see anything?

help stack doesn't tell me anything about untruncating argument values.

We don't have a configuration option for this, it's hardcoded and it was never requested. It is truncated because at some point it needs to be truncated (we need to limit the size of responses plus think about recursive data).
