That's not true in newer versions. It selects sinks based on what
decoder was selected and other heuristics, it's quite complicated
actually.

This e.g. makes sure that vaapisink is chosen when vaapidecode is used,
that is, the best possible decoder/sink combination.


It will also select sinks that support compressed formats if that is
possible.
