Your second point raises an important consideration about defining terms like "better."

For instance:

"The new UI is better." "This code is better."

However, without clarification, "better" can be subjective and may simply indicate a difference rather than an inherent improvement.

Considering the previous functionality of the UI/code, the new "better" version should demonstrate significant enhancements to be worth considering.

Yes. The problem is the cost of the change often isn't suffered by the people making the change, and it's too easy to make changes.
