Nowdays basically any professionally produced book is made in Indesign. And text wrapping is semi-automated. It's automated but checked for issues and fixed manually. Indesign has two text wrapping algorithms paragraph composer that tries to balance whole paragraphs and line composer that only checks line by line.

Surprisingly in the high-end the less automated line composer is used a lot more. It requires more work but human decisions lead to best results if done properly.
