Why repeat precompilation when running 'test DifferentialEquations'?

I’ve just installed v1.9.2 (became available for Manjaro), and reinstalled the DifferentialEquations package. Out of curiosity, ran Pkg.test on it (actually just from Pkg manager prompt) and it repeated the precompilation step.

I assume this is because test starts a new project?

From what I understand, test turns on bounds-checking unconditionally, which disables @inbounds annotations and may require recompilation
