Migration support for a contrib module would best go into that module.

We're not adding new features in the 1.x branch but will revisit this for 2.x.

I'm not sure it's worthwhile using the Migrate module for Statuses though. The only documentation I see for the Migrate module is the example module included in the package, and it includes queries that explicitly grab data from the old tables. If that's all you're doing, you can just save stuff directly to the {statuses} or {statuses_comments} tables with an INSERT INTO ... SELECT FROM query as most sites won't be doing much else when a status is saved. Anything more complicated than that probably requires custom code for each site in order to match up e.g. recipient IDs, attachments, or whatever.
