This could be very dangerous, depending where an exception happened. Variables can contain critical secrets, like your TLS keys or a user's password and if your stack trace printer isn't aware of what should be redacted now you've got that in your logs.

Agreed, but this would help force developers to deal with treating secrets with the care they should have been treating them with all along, in my opinion.

PowerShell's [SecureString] type is something of a step in the right direction, although its execution is lacking in some respects.

In any case, stack traces should _always_ be treated as secrets.
