While that is certainly an option, it has several drawbacks at this point:
- IIUC it would require creating a new profile version and adding support for reading that in addition to the current one.
- That's certainly a larger change and I wonder if it would be appropriate for backporting to the 19.x branch.
- I doubt I'm up to implementing that, while my proposed patch is just fixing the current format.
