How to understand the word "taint" in the new APIs taintObjectReference and taintUniqueValue?

When I'm translating the docs reference/react/experimental_taintObjectReference and reference/react/experimental_taintUniqueValue into Chinese, I'm thinking the deep meaning of the word "taint".
The explanation of the "taint" is to damage or spoil the quality, or the effect of something bad or unpleasant that spoils the quality, which carries a somewhat negative connotation. However, considering the documentations' description of the APIs, it's difficult to detect any negative sentiment. In terms of meaning, it appears that "taint" simply signifies the marking of something with some special behavior.
I understand that Kubernetes has related concepts regarding "taint", but I feel that these two cannot be directly equated. I would like to know how React describes the meaning of "taint"?
Thanks a lot.

Beginne mit den referenzierten Dokumentationsseiten: reference/react/experimental_taintObjectReference und reference/react/experimental_taintUniqueValue. Lies die vorhandenen Issue-Kommentare, um zu verstehen, ob die Terminologie geklärt wurde und auf welche Formulierung man sich geeinigt hat. Erledigt ist die Aufgabe, wenn eine klare Erklärung von „taint“ für Übersetzer dokumentiert ist, sofern eine konkrete Dokumentationsänderung identifiziert wurde.
