In terms of a PR temp, maybe something like this would be good:

Experiences from the parse server repo, after which this template seems to be shaped:

• Sometimes the checkboxes at the top are misunderstood as "check which ones apply" instead of the intended "all are required, so make sure all are checked". That comment section of the template should therefore be rephrased to male that clear.

• It still (although much rarer than pre-PR template) happens that PRs are created without corresponding issue. Issues should always be mandatory for a PR, because a low-level solution should be derived from a high level discussion, which should take place in the issue thread, not in the PR thread. This template is lacking that, but I think the server repo template has that as required checkbox.

• TODOs at the bottom are repo specific and important, to reduce the risk of PRs lacking required chores. It proved to be successful with the server repo. I think at least each of the client sdk repos also should list its specific TODOs at some point, and will therefore require a specific template.
