create-project includes an unnecessary .cow directory

[madmatt]

I don't understand the purpose of the .cow directory - I know what cow is for but I don't know why there's a file in there that's added to every project that starts with composer create-project silverstripe/installer. If the file is required, could it be ignored by composer maybe somehow?

Yes, we can add it to .gitattributes so it's ignored in tagged distributables. It's there for us to do releases with, but that always happens from a dev version which is not affected by git attributes rules.
