I agree: a "glue" layer is not useful (mostly obsolete), and I also
never had to use it.

Adhesive layers (note: they are not named glue layers) are certainly a
very specialized feature.

On the other hand, they are paired layers.

Please see them like layers which can be used to draw some specific
things closely related to a footprint, like its thermal radiator, a
carbon paste layer ...
