Presumably this is to avoid regressing user mods to members of /etc. But there's a way to deal with this. Years ago I took a class in SMP/E software maintenance (Amdahl taught it). One of the exercises was to APPLY a USERMOD then attempt to APPLY service that conflicted with the USERMOD. It failed. RESTORE the USERMOD; APPLY the PTF; then re-APPLY the USERMOD. Why is /etc/magic not handled this way? (I'm confident that we have no user mods to that file.)
/etc is the standard location for system configuration information. In the same way you don't use SMP/E for SYS1.PARMLIB, you wouldn't want to use it for /etc.
I'm not sure how it is packaged in z/OS, but in general I think it is incorrect to replace the /etc directory when installing a new version of the operating system - the same way you would not drop in a totally new SYS1.PARMLIB.
