Currently it's not possible to use .Site.Pages in Conten adapters, while the reaseon is stated quite clearly, I was asking myself if that need to stay that way. Tgere already is .EnableAllLanguages which changes the runtime behaviour, maybe a .EnableAllPages would be possible as well.

Use case(s)

Allowing access to site pages during the execution of a Content adapter would allow to generate pages bases on existing pages. This in tur can allow different things like:

• Pages for combined Tags (a feature asked for from time to time 1, 2)
• Another way to generate archive pages
