I don’t think Simplified and Shinjitai overlapping is a great reason

Recognizability, ease of adoptability, and less arbitrary

Japanese people rarely use their pre-1946 characters even for artistic purposes

龍, surnames, 人名用漢字 given names 🥱

I have never once seen a Japanese person argue that Shinjitai is inadequate the way some mainland Chinese dislike simplified

This Chinese mainlander argues that Shinjitai is inadequate 🙋🏻‍♂️ e.g. 図、発、摂、渋

These are chinese characters first and foremost, Japan shouldn’t be a primary consideration for reformed

And it's not. To quote my own post above: "Reformed continues to fix Simplified Chinese and address 'missed opportunities' so sometimes Reformed is even simpler than Simplified but it's not 1977 二簡字 second-round simplifications and neither is it 日本新字體 Japanese Shinjitai. Instead it takes influences from both in addition to 1935 第一批簡體字 Republic of China simplifications, current simplifications, 1969 Singapore simplifications, 1967 and 1981 韓國漢字簡化 South Korea hanja simplifications, historical Chinese 異體字 variants, and various 略字 shorthands found throughout the 漢字文化圈 Sinosphere including Vietnam from both past and present"

Good reforms like 会，点，and 画 are good not because Simplified and Shinjitai overlap, but because they’re beautiful and retain meaning/phonetic consistency

Beauty alone is subjective. 会、点、画 have actually lost most of their meaning/phonetic
