1. Is this intentional? If so, what is the reason (performance, spam, something else)?
This function was put into the package in 2018 and nor I remember nor could find a trace in my records, why it's been done so. Perhaps it was something experimental, because it's not even mentioned in the Update file.

2. Would you consider removing the script, or making it optional, in a future release?
I will remove it in the upcoming new version of miniBB. You can do the same. Not sure if I would remember the reason, but for now, I couldn't find it.
So far, thanks for bringing this up!
