If you set CONFIG_MODULE=y and build SCSI we assume you could have a

This should be implemented like "Library routines" and only added if such a SCSI driver module is actually selected. Why can't it at least be a visible option in the menu? (Although even then it looks like it's impossible to disable).

There's out of tree modules to consider.

Ok, I propose we make dozens of modules default 'm' in case an out of tree module requires it.

SCSI_SCAN_ASYNC ("Asynchronous SCSI scanning"): "You can load the scsi_wait_scan module to ensure that all scans have completed."

It looks like SCSI_WAIT_SCAN is pointless unless SCSI_SCAN_ASYNC is selected - so it should depend on it:
