I imagine that in some instances you could use ribbon EDM to get sharp corners AND better surface finish of convex surfaces.

Couldnt a mill with a proper articulating head be set up come in with a bit that has an angled tip, like the shape of a drill bit but with an angle less than 90deg, and finish down each face of the inside corner? I imagine itd still leave a rounded area where the walls meet the 'floor' of the part, but if the goal is perfect 90deg walls that might work....supposing a bit can be made that will make that kind of cut....

how about broaching

Also using a shaper or a slotting machine

What about a 90 degree angled cutting tool?

That's a great idea! A 90-degree angled cutting tool can indeed be effective for achieving sharp internal corners in certain materials.
