Show alternatives to outdated extensions

What kind of feature do you want?

In the detail view, alternatives to an outdated extension could be shown up.

For instance, I'll leave open how this can be done.

One way to do this would be to use the tags and to determine a notion of similarity towards other extensions.

Another way would be to let maintainers explicitly specify which extensions can be migrated to their extension (similar to the specification of incompatibility). The latter should then also take versions into account (from_version/to_version) which maybe overcomplicates this approach.

Another way to do this is to use frequent pattern mining based upon the sequence of page visits, thereby answering which (alternative) extension is likely to be downloaded after visiting an outdated extension.

An easy catch would be to just point to the TER search page, thereby querying for the tags of the outdated extension.

What are the benefits?

• Show up that there is an alternative.
• Trick users into supported extensions which receive security updates.

Add some use case

E. g. the outdated extension tq_seo can be seemlessley upgraded to metaseo via a documented migration path.
