Ran some benchmarks against different minifiers and discovered that the restructuring can actually perform worse after compression, and even if it sometimes is better - it runs much slower.

Two main points:

• Perhaps it might be worth considering changing the default to false?
• Perhaps the focus should be redirected towards actual compression speed vs compression ratio as there is more room for improvement there

some added context: general purpose compression is used on 85% of websites according to:
