Just keep using the proper Postgres project if it makes more sense to you. But notice that this isn't just a strict translation, it actually makes changes (moving from process to thread based design, for instance). Time will tell if people find these changes beneficial or if the original remains preferable.

It's also worth noting, that while you are able to use LLM's to produce your own translation, he's actually done it. There's value in actually putting in the work.

This isn't a unique situation at all. Many Postgres extensions are developed and maintained by a single person, and may therefore be avoided by more conservative users, even if they offer some technical advantages. To each, their own.
