Has anyone thought about printing narrower lines in order to get sharper corners? Once Linear advance or Pressure advance is activated, you don't get bulging corners anymore... but can we do better?

Has this been implemented anywhere yet? Does it have a name?

Interesting. This is new to me and it looks like it could work. It could be usefull if you print with 0.6 nozzle at 0.6 mm width and then in a corner narrow it down to 0.4 mm

Exactly. Cura already does variable width lines but mostly to be able to print narrow sections or to fill narrow space between outlines. It could also use this technique to do sharper corners. Unfortunately to my understanding, firmwares don't yet support G1s with variable target extrusion rates. Ie. start extrusion rate = X and end extrusion rate = Y. Using this feature, my idea could be implemented in just 5 G1s per corner vs 1 for non-sharp corners.
