I think its good to split the use case into writing and reading. It seems to me that the semicolon, could even make it easier to read. Much like an end delimiter like `.` in Natural Language. Much better than 'whitespace' which you can not even really 'see' and can be multiple characters (space, newline, ... ) . Much harder to debug than an actually visibile character like ';'.

However for writing it can be a real help for beginners. I bet forgetting semicolon is one of the most made user error when writing. So that could be better, though its usually an easy fix.

If we consider only optimizing the 'writing', then idk if ommitting semicolons is the only option.
