THIS! I've been maintaining a Neocities website for almost three years now. While, being a software engineer at heart, I still ultimately versioned the offline copy of my website via Git(lab), it's liberating to not have to wrestle with a git workflow just so I can hide my works-in-progress.

Also, in my case, a matter of branding. While I'm not trying to promote my content (a bunch of short stories and illustrations) so heavily, it just felt wrong for them to reside in Github/Gitlab subdomain. The closest I would've considered Git* pages is if I was doing sci-fi stories and that is still a "maybe". At the time I started my project, I was also worried I might run afoul of some content policy these Git platforms might have given that my website is not exactly for their demographic.
