Question about subparts (3626bs01, 3626cs01)

[Manfred Schaefer]

Hello,

I noticed that for the printed Minifig Head with Hollow Stud, there is a subpart that contains the stud and the back of the head (3626cs01).
For the printed Minifig Head with Blocked Hollow Stud there is also this subpart (3626bs01), but here it is marked as obsolete.
What is the reason for this here?
Can't this subpart be replaced by a modified version of subpart 3626cs01?

Greetings


Manfred
