The purpose of the presets proposal is not to inform readers but to help
users make a decision about which features to enable when writing a
Parquet file.
For example, a user of PyArrow could, instead of passing an elaborate
set of flags, call `pq.write_table(tab, 'file.pq', preset='2024-01')`.
Regards
Antoine.

How can a reader know that it has the tooling to read a file with this
approach? What is the hesitation to change version numbers?

What's a preset? Could you describe the idea in this discussion so we can
keep it in one place?
The concept was introduced earlier in this thread by Antoine.
