Folders cannot have their case changed once they have been created

I created a branch with the name Bugfix/Whatever. I am wanting to change this to bugfix/whatever, but there seems to be no way to do so - Even if all my branches with Bugfix/ get deleted, any new branches get the 'Bugfix' casing instead of 'bugfix'.

Not a huge dealbreaker, but we use /bugfix/' on GitHub and it's creating issues around my branches remembering where to push to since I keep having to manually change it.
