Is there a specific set threshold for the number of times various users have to ask "How do I vote to migrate questions to a site that doesn't appear in the list?" before even, say, an "Other" button that links to the "other reason" form is added to that list?
It's obviously confusing, please fix it already.
And on, and on. If you have an actual specific, finite number of complaints about the same exact thing that you need to see before you are convinced that it's an issue, please let me know, and I will search harder to collect them all here until I reach that threshold and you fix it.
