As already discussed in Discord it seems all fine.
And as you've tested everything there shouldn't happen errors due to param default value changes.
But it's of course something we need to rethink in some cases if switching from something like nil to the zeroPos for a position argument could be something which makes it harder to debug as it won't throw an error and just dump/create something at the corner of the map under the water surface.
Overall it looks good to me and the mentioned default value changes would be something we can easily adjust when we encounter some unwanted behaviour.
