Input sequence for U+488E 䢎 contains a lot of redundancy.

Currently the input sequence for 䢎 is: (1132|113112)(454|4454|4554). Unless I have missed something here, I would have thought 1132454 would be sufficient, making it the same as for U+8FDB 进.

• (1132|113112) allows for 开 (modern) and 幵 (olden).
• (454|4454|4554) allows for ⻌ (simplified), ⻍ (olden), and ⻎ (modern).

I don't like prescribing certain standards over others.

Arguably it makes no sense to allow 113112 幵 and 454 ⻌ simultaneously, but excluding such cases would take a lot of effort, and make the data set less readable (and maintainable).

进 on the other hand is a strictly simplified character. Therefore only the simplified form of the radical is included.

That makes sense.
