As it stands the migration path is to get the user to ask a moderator to migrate it. If it was truly "good" then I wouldn't have a problem sending stuff their way now that the "beta" is gone.
As a 20k user I believe you have access to https://superuser.com/tools/posts/migrated/stats.
We can see that 16 questions were migrated to ServerFault. There have been no moderator-actioned migrations to Software Recommendations (there might have been 1 and it's not shown on that list) but typically the kind of questions we get are of pretty low quality and would immediately get closed. We'd prefer to apply the golden rule of question migrations in any case.
I'd support changing the migration target list if we can establish that there are a significant number of questions that meet their rather stringent question quality guidelines. I'm not sure what search terms could easily find and catalogue them though. It might be a thankless task to catalogue them.
Wordpress or Raspberry Pi might arguably be better targets than Software Recommendations if the stats are anything to go by, but they're not better by much, particularly if you take rejection ratios into account.
For those with less than 10k rep:
