S1:
When database normal shutdown, and clog file missing, the database cannot restart. And if make a zero clog file, database started but may cause transactions lost.
S2:
When database crashed, and clog file missing, when database restart, it will try to recover. And everything is ok
So I think we may improve the database more reliable in some scenarios, e.g. Only clog file corrupted or missing, like S1

Clog file cannot disappear as a result of a crash. What makes you think otherwise?
