Comment (by goldfire):

 Fair enough. But I'm still worried about runtime implications of signature
 sections, as described in the Phab:D1185 comments. Visible type
 application doesn't have that problem. If I'm right in supposing that
 signature sections potentially have runtime implications, I personally
 would never use/recommend the feature.

 Agreed that sometimes a signature section is more convenient for the
 programmer than figuring out the right visible type application.
