Disabling pull mirroring for external repositories

Hello there,

I was setting up mirroring for external (private) repository hosted by bitbucket and I found this
https://gitlab.com/gitlab-org/gitlab/issues/10361 while reading the regarding documentation.

I wanted to ask you whether disabling pull mirroring for external private repositories (on GitHub) is going to affect also private repositories hosted by bitbucket.org or not?

So I went through the docs again and here is what I found:

Having external private repository when using GitLab CI was part of Premium (Silver) Tier features. This was later set free for more than year and will remain free until 31. March 2020. From that time on you will need Premium (Silver) Tier subscription again, thus you have to pay 19$ per user per month (when billed annually).
