I don't think we want to add in the functionality of deconvolving by the pixel to get back to the raw profile that would have been drawn with `method='fft'`.  However, I think you're right that it deserves a discussion of what it means to interpolate in image that was drawn with a pixel-convolving method.  i.e. that the resulting profile will include the pixel convolution, so you wouldn't want to do so again if you use this as a PSF model for example.  I'll add a para about this.
