35 * Declining stays offered whatever the permission. Bitbucket lets the author of a pull request
36 * decline their own with no more than read access, and the permission response says nothing about
37 * who opened this one — so withholding the control from the one person entitled to it is the
38 * worse of the two mistakes. Commenting and reviewing are not narrowed either: read access is
39 * enough to say something, to approve and to ask for changes.
40 *
41 * Asking for a review is left open for the same reason: Bitbucket takes a reviewer set from the
