And no, its not that hard once you learn. Except, now its a never ending chore when it was an appliance. Instead of a car you have a project car.
Can confirm.
Also, not everyone who wants to share content publicly has a domain name with which to do so, or the kind of Internet connection that allows running a server. If you include "hosting" by using a hosting provider... it's perfectly possible (raises hand) to not even have any experience with that after decades of writing code and being on the Internet. (Unless you count things like, well, GitHub and its services, anyway.)
# locally
ssh git@example.com
# server
mkdir repo.git
cd repo.git
git --bare init
# locally
git remote add origin ssh://git@example.com/home/git/repo.git
git push origin master
Just store the repo and access it with your account.
The whole git@ thing is because most "forge" software is built around a single dedicated user doing everything, rather than taking advantage of the OS users, permissions and acl system.
For a single user it's pointless. For anyone who knows how to setup filesystem permissions it's not necessary.
but if you're just looking for a generic place to put your code projects that aren't necessarily intended for public release and support (ie. random automation scripts, scraps of concepts that never really got off the ground, things not super cleaned up), they're not really for that - private repositories are discouraged according to their FAQ and are very limited (up to 100mb).
You don't need a one size fits all solution...
Until the AI scrapers[1] come for you at 5k requests per second and you're doing operations in hard-mode.
1. Most forges have http pages for discoverability. I suppose one could hypothetically setup an ssh-only forge and statically generate a html site periodically, but this is already advanced ops for the average Github user
