I think it's customary for GIMP to warn when operations initiated by the user will be performed slightly different than the user might expect.
An example is when scaling indexed images. It then says: "Indexed color layers are always scaled without interpolation. The chosen interpolation type will affect channels and layer masks only."

This warning still being present in master was a bug. Scaling; along with gaussian blur, unsharp mask, rotation, flattened down text layers and more ops, now treat indexed mode in such a way that if the palette contains relevant entries for desired in-between colors the scaling code in GEGL, and thus GIMP uses them.

The warnings is now gone in master, to get the old result - of course nearest neighbour can be chosen manually :).

All right.

Regardless, some sort of warning when saving an image with transparency as JPG would be user-friendly.
