Archive imports have been disabled because Twitter have disabled the kind of archive that Forget knew about.
The new archive format is much larger, because it includes media, and it is a privacy nightmare because it includes everything twitter knows about a user. DMs, ad targeting info, the whole mess. The old strategy of uploading the zip file and letting the server figure it out is not going to work.
The plan is to extract and parse archives in the browser, and send batches of statuses to the server.
Individual issues for tasks to be done as part of this project are #458, #459
