Re: Granting SET and ALTER SYSTE privileges for GUCs

I just came across something odd in v12 that is still there in v13:
ExecGrant_Parameter uses InvokeObjectPostAlterHook not
InvokeObjectPostAlterHookArgStr.  This seems pretty inconsistent.
Is there a good argument for it?

... or, for that matter, why is there any such call at all?
No other GRANT/REVOKE operation calls such a hook.
