Commerical grade refers to the temperature range the component is tested to work. Amusingly it is the lowest grade where you can get industrial grade, military grade or even space grade components.
I tried to work with those lattice parts once but they were so tiny (0.3 or 0.4mm pitch bga) basically undoable by cheap Chinese hobbyist board houses.

At the bottom of the page you'll see a link to someone who followed your suggestion. Now that looks hard. :)
