But, that's exactly what happened with segwit. Why is that worth doing but increasing the block size is not?

[eklitzke]

The main thing Segwit fixes is transaction malleability (which is necessary for Lightning).

If I recall correctly, Segwit was a prerequisite to Lightning. A block size increase is not.

[SuddsMcDuff]

You recall incorrectly. A malleability fix was a prerequisite to Lightning. SegWit is just one of many possible malleability fixes.

[Ajedi32]

Were there any other serious proposals for fixing transaction malleability without Segwit?
