Aside from mipmapping, is there any practical use of having a different texture filter for min and mag?

Depends on what you want. I can see various effects being pulled with LINEAR one way and NEAREST the other, say.
Well, you can use the texture LOD value to have some nice effects with mipmaps.
I think using GL_NEAREST_MIPMAP_NEAREST comes in handy for this case.

I am just trying to widen my horizons here because I do not seem to have enough knowledge/experience to find of a use of having say GL_NEAREST as mag and GL_LINEAR as min or any other combination.
Certain types of textures look better when magnified with GL_NEAREST instead of GL_LINEAR. Basically ones with sharp color variations and lots of straight edges, for example the panels on the surface of a star destroyer. However, when they are minificated you still get better results when using linear interpolation and mipmaps.
