Teflon became a thing because it's both hydrophobic and lipophobic. There are lots of hydrophobic surfaces that work very well until you get dirt, finger oils, soap, or just about anything that isn't water-soluble on them. There may also be an issue here with friction damage.
Hopefully the technique here can be adapted to practical products.
The technique is extremely flexible. I'm sure they'll figure out an etching pattern that is both extremely lipophobic and hydrophobic. Only hydrophobia has many applications already.

Hydrophobicity alone is only so useful.
