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

参照されているドキュメントページから始めます: reference/react/experimental_taintObjectReference と reference/react/experimental_taintUniqueValue。既存の issue コメントを読んで、用語が解決済みか、どのような表現で合意されているかを確認します。具体的なドキュメント変更が特定された場合、翻訳者向けに「taint」の明確な説明を文書化すれば完了です。

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.
