+* ``pyodide_${YEAR}_${PATCH}`` -- This avoids potential confusion between e.g.,
+  ``314_0`` and Python ``3.14.0``. On the other hand, it makes the link between
+  ABI and Python minor version ambiguous.

+* ``pyodide_${MAJOR}_${MINOR}_${ABI_PATCH}`` -- this would handle a future
+  two-digit major version, but the ABI patch version would be too easily
+  confused with a Python patch version e.g., ``3_14_0`` seems to imply Python
+  ``3.14.0`` specifically rather than Python 3.14.x.
+
+* No ABI patch version -- we hope never to need the patch version, but it's
+  good to be prepared for unforseen problems.
