It's in the personal name FAQ not to add cross references for headings with incorrect dates. Except that people like them because they aid in string matching based authority control.

Subject: [PCCLIST] Reference from form with incorrect date?
If a birth date in an authorized access point is incorrect (not just possibly but definitely, documented as incorrect), we are supposed to change it. But are we, or are we not, supposed to add a reference from the old, incorrect form? Coded $w nne or $w nnea, depending on circumstances?
In the case I am working on that would be:
100 1 ...... $d 1841- ...
400 1 .......Sw nne $a ... $d 1842- ...
It is my recollection that it was the policy NOT to do so. I certainly found an example, contributed last year by LC, where a death date was added, a birth date was corrected, no new reference was made from the incorrect form, and a reference from a DIFFERENT incorrect birthdate (used when the heading was originally created) was removed, although it had been carried on the record through the change to RDA. If you are interested, it is lccn n 97033212, which now reads: Cohen, Larry, $d 1936-2019.
However, I also have a vague recollection of reading a recent discussion (on this list or some other) in which someone suggested it was OK and perhaps advisable to make such references. Or was that with regard to something else?
I would be happy if someone could answer this definitely one way or the other.
