That's probably the most straightforward solution, yes.

Paragraph movement within code is "non standard": I'm sure some users
use it regularly, but I'd expect the vast majority never uses it, and
all programming major modes I know don't seem to care about
paragraph movement.  Many do care about paragraph filling, tho.
So I'm pretty sure that the paragraph-* settings here are meant
specifically for filling and not for movement.
