So, I need to update all the tools to support QUERY, or I need to update all the tools to support GET/body.

So, either way, I need to update all the tools.

Just fix GET.

The point is that if you do that, you end up with lots of undefined behaviour in existing software that has not been patched yet.

If you make it a whole new request method, existing unpatched software should just respond with "Method not allowed".
