As long as it remains strictly opt-in, I think it's a good idea. However for the niche group you mentioned, this could potentially chase them away unless they know they won't be tracked.
A more tailor-made experience could help in retention, but it needs to be combined with both bot and human assistance from the minute of signup. Welcome and help those new bees :)
There will always be frontends that don't track, at least hive.blog
I agree with the second paragraph, a tutorial would help a lot already. Human assistance is difficult to organize well in a decentralized manner and without pay, but should be tried of course. Discord works well, but reaches few users, most give up before they go there.
