The evidence image, which is simply a code chart excerpt, is insufficient. While the link to the CNS 11643 website is better, it also is insufficient. A dictionary entry or book excerpt that explains its meaning or shows the ideograph in context is desirable.

Agree with comment by Ken Lunde.

IRGN2486 (TCA's submission for WS2021) indicates that the evidence image is from the household service database, from which the name on each person's ID card is printed. It is not simply a code chart; it is an official government document with legal effect. For further explanation, please see IRGN2546.

Is still feel that such instances of Radical #162 should be normalized to follow Taiwan regional conventions.

TCA understands your viewpoint. (From my perspective, I agree with your point. )
The issue is, when the characters are normalized, they might not be what people or scholars who use them actually need. TCA has been deliberating on how to strike a balance between the two.
When submitting the WS2024 character set or others, TCA will try its best to select forms that follow Taiwan regional conventions.
