What performance and memory usage impact do these have?
I run many small scripts and already find startup times slow.

We should reduce stack size limit instead to avoid big backtraces ;)

Jokes aside, this may be confusing and break compatibility because of
existing tools which process backtraces (perhaps generic and not limited
to Ruby).

NACK.  This makes searching for users with similar problems more
difficult and makes error messages difficult for maintainers to
decipher.
