GATK Survivor : what tools should we keep, rewrite or remove?

* 1. For each tool listed below, please indicate what we should do. If you have never heard of a tool or don't care what happens to it, just don't check anything in that row. 

Keep = keep it in the toolkit as is. Check this option if you have used the tool and it works well enough (with the possibility of improvements to be added on request). 

Rewrite = rewrite this tool from scratch. Check this option if you think the tool's functionality is valuable but the tool itself does not work well enough to be usable in its current form.

Remove = delete it from the toolkit. Check this option if you think the tool's functionality is not useful or if you prefer to use a different tool from another toolkit that has the same functionality but works better for you.
