I think it's better to count the number of child nodes in the begin - it's one-line and has 1+ children they must be separated by semicolons, right?

Right! And it should have been accepted if begin block has multiple statements, whether one-liner or multiple-lines. I also added several test cases and modified this implementation based on it.

Fixes rubocop#10004.
