It's called the Internet Compression Algorithm - you can compress the entire Internet into a single bit.

Seriously - I think what happened is when SegWit was developed, it was developed with the design constrain that it must be doable with a soft fork and that is why it became overly complex.

Maybe they should have put some more thought into whether or not that design constraint was justified.

Sometimes instead of only asking if you can do something, you need to first determine whether or not you should do that something. Simpler solutions make it easier for future developers to properly implement, and with a crypto-currency where money can literally vanish because of coding mistake - that is important.
