V源特有部件「〾冘」字形及认同疑问

[asgsdbrseg]

V源字形与其他源差距较大，且有一组认同与其他组不同。
同时V源还有大量的「冘」作为部件存在汉字中，不烦举例。
V源特有的「〾冘」部件是设计差异，还是具有字义上的区别？
如果保持认同，是否需要固定一种模式作为UCV，还是视情况在「冘」「⿺冘丶」或更多字形中随机选择？

The question of the design of "đăm, đem, etc." phonetic and semantic component is complex and would require some research. As you can see in the image below, there are a number of shapes in common use

Scholars such as Nguyễn Quang Hồng believe that this form is ultimately derived from 酖 (U+9156), either as a direct abbreviation using 冘 or as 冘 plus additional strokes to clarify the semantic (https://www.nomfoundation.org/nom-tools/Tu-Dien-Chu-Nom-Dan_Giai/Tu-Dien-Chu-Nom-Dan_Giai?uiLang=en). For minimal semantic distinction, we would probably distinguish characters composed with 冘 alone, from 「⿺冘丶」and the variants. So, for example, VN-0449E should be distinguished from U+449E because the shapes and meaning are not identical. Without further analysis, it's hard to say whether the variations are random are not, but my impression is that the form used in VN-0449E, VN-25AF9, etc would be most common.
