In practice
Keep it curated. A link dump of every URL helps nobody; a structured page grouping the main hubs is genuinely useful on large sites.
Treat it as an internal linking asset rather than a crawl fix — the XML sitemap already handles discovery.
Why it matters
It gives deep sections a shallow entry point for both visitors and crawlers.
On sites with weak navigation, it is often the fastest way to reduce crawl depth without a redesign.
