WordPress address and Site address settings don't allow trailing slash

[nomulous]

Most WordPress blogs would be found at x.tld/blog/ or something similar. Why don't these fields allow trailing slashes? It's especially inconvenient because the header of most themes links to this URL, which means there's a client-side redirect every time it's clicked.

This is to avoid double-slash issues in permalinks. The theme needs to add a trailing slash to the site's front page, and the permalink structure should have a trailing slash at the end of it if you want other urls to enforce that preference.
