The issue is that it could still be abused against small instances.

For example, I had a bit less than 10 bots trying to signup to my instance today (I had registration with approval on) and those account are reported as instance users even though I refused their registration.

So even if you don't allow spam accounts to get into your instance, you can easily get blacklisted from that list because creating a few dozen thousands account registration requests isn't that hard even against an instance protected by captcha.
