[Feature Request] Option to make .git not read-only in cloned repos

Hi git folks,

Honestly I'm not aware of the reason behind .git being read-only, but I'm sure there is one.

However, I'm sure that a large percentage of developers out there will agree with me that having to use force (-f) to delete every cloned repo is annoying, and even worse, it creates the bad habit of always force-deleting everything.

Would you find reasonable to add an option to keep .git writable on cloned repos?

PS: I'm not subscribed to the list, so please CC me on replies.

Thanks! Albert
