Many bashisms tend to improve maintainability. For example, [[ ]] helps prevent quoting errors, and >() is more foolproof than creating temporary files or fifos. I don't see a big performance impact in supporting some of these extensions in an extended mode for dash, to get a bit more speed than bash without doing a lot of pointless porting.
