Is it possible to update just a component in a fprime deployment? Can each component be a shared library?

Right now, building a FPrime app creates a single big executable, and I deploy it on hardware.
Lets say I modify a component. Is it possible to patch update just this component to the hardware? I want to avoid uploading the entire deployment.
In some component based frameworks, each component is a .so file. This way we can just reupload the .so file corresponding to the component, everything else stays same. Is something similar possible with Fprime?

Yes, you can compile each component as a shared library. Use fprime-util generate -DBUILD_SHARED_LIBS=ON. However, we've not explored the practical implications of this. You'd need to make sure interfaces (FPP files) don't change, only the internal set-up. You may need to add some additional link dependencies.

Most projects prefer a monolith upgrade, and bsdiff + bspatch to reduce upload sizes.
