Agreed.
Although now you mention it, perhaps the normative specification
*should* explicitly mention that C_Initialize() may be called in a
child¹ after fork() and should function correctly without disrupting
the operation of the same module in the parent process.
That requirement was always *implicit* because of the recommendation
in the usage guide. But if the recommendation is removed, no hint to
implementers will remain. And yet there will obviously still be software which implements the (old?)
recommendation.
