Probably comes down to either inline assembly or dependencies, or both.

Yup, I don't know if Gimp does it, but speeding up image filters is basically the perfect scenario where inline assembly can have huge payoffs.
These days, compiler intrinsics are typically the best approach to that stuff. Mostly.
Linux builds of GIMP already ran on arm64, as well as a number of even weirder architectures (like mips or s390x).
