>gluing down CMOS ... seems surprising

This is because without securing the battery, it becomes the most-likely RMA reason (shipping can unseat the battery).

For the zero/one time in the computer's lifetime that it requires replacement, there's a chemical that will remove the glue's attachment.

Very good point. I know there’s a “clip” there to keep it secure, but certainly could get moved during shipping.
