Materials vs Textures in Asset Bundle

Does it make much difference if I include a material in an asset bundle with the textures or just include the textures and make the material at runtime?

I'm using LWRP, and these materials are using the lit shader. What I'm asking is will updates to LWRP cause any issues with the materials reference to that shader? For example if they change parameters in the shader.

I need to be able to update Unity/LWRP without ever rebuilding the bundles

 

I would create separate bundles for materials and textures.

The reason for this being, that textures often consume a lot of space, but change relatively seldom. Materials get tweaked more often in my experience and if these two asset types have been separated, if you rebuild bundles, Unity won't repack the huge texture bundles again due to its incremental build system.

Which results in faster build times and fewer bundles to deploy in an update.
