I have a similar feedback as Moin.
Super useful. It saves a lot of time and energy.
There are, for sure, edgy cases where the same word is auto-linked too many times in guides.
Possible suggestions:
- Limit the number of times the word is linked – at least once per paragraph or ideally once per section if feasible).
- Exclude self-auto-linking in the topic that the link is referring to.
- Exclude auto-linking in headings
- If it still doesn’t help for some guide, we can see how to improve the text.
Overall, it’s really good and convenient. I would be careful about what words to add, though. [1]
About what to add, let’s see,
- A few reference guides for users, moderators, admins, and developers (and potentially the index ones; maybe it’s too early for that, though).
I wonder what the statistics are. Based on how often a link is referred to, it could be a good idea to add a keyword for that link. 
For example,
trust levelwould be likely overwhelming without any control. ↩︎
