bpy.ops.fluid.bake_all() always overwrites

I am running this command when I have already baked previously and I see that it still bakes overwriting the previous baking. I thought that baking was skipped when the cache_fluid folder was created.

I thought this command would work only if there was no other cache folder with that name, and, in case there was other folder, it would just stop, but in my case is overwriting the previous folder.

Is there a way of preventing this? Thanks!
