Removing the ability to track on-topic questions about how to use or implement specific project management tools would be A Bad Thing™.
The Underlying Problem
The problem isn't questions about using tools, it's with questions asking for tool recommendations. By definition, the latter will solicit polling, debates, and unsubstantiated opinions.
On-Topic Tool Discussions
However, there are many tool-related questions that have a reasonable chance of being answered by applying a little scope. Consider an imaginary question such as:
My kanban doesn't contain a column for enbiggening therbligs. I've tried adding an enbiggening column, but kanban cards are queuing up in QA column without any therblig-related cards being pulled into enbiggening.
How can I properly represent embiggening on the kanban, and quantify the flow issue based on the information on the kanban itself?
Granted, this imaginary question assumes some context, and might have multiple valid approaches (this is a generic issue with any practice that includes soft skills and process analysis), but it is nevertheless about how to use or implement a given tool. This seems quite constructive.
Fix the Wiki and Handle Off-Topic Questions Normally
Rather than getting rid of the tools tag, we could update the wiki to reflect why one should apply the tag, rather than using a generic definition of what a tool is. Even if you can tag each question with a specific tool tag (e.g. kanban or kanban-card), having a superset tag may be quite useful.
In addition, questions marked tools will remain subject to the same sensible criteria as the rest of the site, and can be closed or deleted if they are off-topic, not constructive, or too listy in nature. We already have a process for handling those sorts of questions, so removing the tag seems like it might be solving the wrong problem.
