If your request doesn’t appear on the list, probably the diff was too big
There’s a size limit for mails to firstname.lastname@example.org, and in general that’s how we read unblock requests. If your mail doesn’t appear on the list, but you do get a bug number back, your mail is likely too large..
In this case, that’s probably a sign that we won’t accept your request without exceptional circumstances. Making so many changes in a package is almost certainly not appropriate for this phase of the cycle.
Do use filterdiff to remove automatically-generated files from your diff before sending it, which increases the chances of acceptance.
Do follow up to the bug if it doesn’t appear on the list; send a short message explaining that happened and why your giant diff should be considered.
Don’t be surprised if thousands and thousands of lines changed are rejected.
