A quick google for "uicr endurance" gives, as top 2:

https://devzone.nordicsemi.com/f/nordic-q-a/23884/how-many-times-can-i-modify-uicr

The thing is that the UICR is only 32 words - so you will (probably) use up the endurance far more quickly than with a decent wear-levelling strategy in Flash..

Again, the need for & effect of erasing is inherent in any Flash - not specific to Nordic:

any particular reason for so old?

According to the InfoCentre, FDS and fstorage were both available back then:

Which SDK version are you using?

In the current version (15.3.0), the options are:

fstorage - basic access; you have to manage erasing, wear-levelling, etc.
https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/lib_fstorage.html
FDS - builds on fstorage; allows you to update records; manages erasing, wear levelling, etc.
