What does this PR try to resolve?

Having sections in the build performance chapter link out to their issues is helpful for:

• giving hope that things will improve
• providing a place for people to subscribe to for updates
• raise visibility for ensuring we get appropriaet feedback (e.g. on degrading the debugger experience)

Noticed this was missing while writing up about this new chapter on the blog post.
