Only in some specific situations. Do you use Maildir++ quota? S= is useful only with it. Do you use Dovecot's deliver? It adds S= automatically if you use quota plugin. W= isn't added automatically by v1.0, but v1.1 adds it (actually I just noticed that the code was accidentally commented out, I enabled it again so the next release will have it). But as long as you're using index files (and you should be), W= doesn't really provide any performance benefits.
