For expediency in getting a green build for better workflow, SLS-438 disabled several scripts.  Among them is s_funcs.  When that script is run the result is:

$ cd dist
$ bash s_funcs
__wt_block_disagg_manager_drop
__wt_block_pantry_manager_drop
__wt_oligarch_log_compat_verify
__wt_oligarch_log_flush
__wt_oligarch_log_get_backup_files
__wt_oligarch_log_needs_recovery
__wt_oligarch_log_reset
__wt_oligarch_log_system_backup_id
__wt_oligarch_log_written_reset
__wt_txn_checkpoint_oligarch_log
__wt_txn_checkpoint_oligarch_logread
__wt_txn_oligarch_op_free
__wt_txn_oligarch_printlog
__wt_txn_ts_oligarch_log 

These are functions that are defined in WT, but never called.  Normally this is a bug that is a coding oversight.  In these cases, most/all of these are probably resulting from cloning some subsystem to make a disagg or oligarch version of that subsystem that can be modified without messing up the "vanilla WT" version of the subsystem.  Sometimes this results in functions not (immediately) being used.  We should investigate all of these, and over time, resolve them by either using them, removing them, or possibly in a rare case, putting it into the exception list.
