-Wdefault means -Wonce or -Walways? If the former, I don't expect many
warnings to be emitted.

I see. For my use cases, this would be acceptable :-)
But I think this should be documented, for example:
"""Currently, developer mode adds negligible CPU time overhead, but can
increase memory consumption significantly if many small objects are
allocated. This is subject to change in the future."""
