Prefetch has been in prod for some time now, we should make it available by default so we can toggle prefetch at the session-level whenever suitable.
The API change should be something along these lines:
diff --git a/dist/api_data.py b/dist/api_data.py
index e2c163b5ff..4f323491ec 100755
--- a/dist/api_data.py
+++ b/dist/api_data.py

This change would make WT-16572 much easier to implement as we would only need to reconfigure the session to enable prefetch instead or reconfiguring the entire connection.
