I'm not fully aware of the implications of this, but if we do want to
change it, it needs to be done on trunk first.

If you get it through review and committed to trunk, I'm open to merging it.

I assume utils/release/test-release.sh would also need an update so
the library gets built?

Thanks,
Hans
