### Rationale for this change PyExtensionType autoload is really a misfeature. It creates PyArrow-specific extension types, though using ExtensionType is almost the same complexity while allowing deserialization from non-PyArrow software. ### What changes are included in this PR? * Disable PyExtensionType autoloading and deprecate PyExtensionType instantiation. * Update the docs to emphasize ExtensionType. ### Are these changes tested? Yes. ### Are there any user-facing changes? Yes. * Closes: #38607 Authored-by: Antoine Pitrou <antoine@python.org> Signed-off-by: Raúl Cumplido <raulcumplido@gmail.com>

Describe the bug, including details regarding any error messages, version, and platform.
PyExtensionType autoload is really a misfeature. It creates Python-specific extension types and using ExtensionType is almost the same complexity.
We should therefore disable PyExtensionType autoloading and deprecate PyExtensionType instantiation.
