What type of request covers anything that is not a defect regardless of customer opinion?

An enhancement request is specifically aimed at proposing improvements or additional functionalities to an existing system or process that do not arise from flaws or defects. This kind of request typically emerges from a user's desire to have a better experience or more capabilities, and it is not influenced by whether the customer perceives an issue as a defect.

For example, if a user suggests integrating a new reporting feature that would provide additional insights into their operations, this falls under the category of an enhancement request. It focuses on extending the system's capabilities rather than rectifying an existing problem.

In contrast, a change request often refers to adjustments made in response to specific project or system needs, which can include both enhancements and defect fixes. A feature request is generally tied to new functionalities that users wish to see but can sometimes involve consumer feedback rooted in perceived shortcomings. A support request, on the other hand, is typically related to assistance for existing issues or questions rather than suggestions for improvement.
