PG staff says its to gauge interest in tool suggestions but that the votes do not factor into the decision making on the tool itself. The problem is the staff is so crazy slow at deciding anything (or responding in general) with tool suggestions the votes use case is almost imperceptible.
EDIT
I don’t want to create another reply as the response is barely on-topic (if that) but @Expert4870 it requires making a decision in some form, to be at risk of making a rash decision
