Since writing the paper is expected to take no more than an hour, given the software is already written, I wonder if they're worried about receiving a flood of submissions. Perhaps it's less of a problem since reviewing a paper should take much less time given their length?
I feel it may be a problem for them since it looks like they try to reproduce the program's setup/workflow, which is (in my experience) more than bioinformatics reviewers usually do:
>Authors are strongly encouraged to include an automated test suite covering the core functionality of their software.
> OK: Documented manual steps that can be followed to check the expected functionality of the software (e.g. a sample input file to assert behaviour)
You can see the checklist reviewers go through in any of the issues here:
Most scientific software probably doesn't already have all these components in place. It would be a great problem to have, to have a flood of submissions!
