Not the same. ARE takes a static content and converts it in an Ada source t=
hat you compile.

Compression can help even on embedded systems because it reduces the size o=
f data transfer.
A jquery-3.4.1.js file is arround 273K. Minified by closure it is reduced t=
o 89K.
If you also compress it, it reduces to 31K.

On slow networks these size reduction make a difference.

There is no waste of resource because the compression is made during the bu=
ild process not at runtime.
I would say the opposite: what you get is smaller in size.

Best regards,
