Deprecated - Drupal core

In Drupal 4, each blog has an XML icon at the bottom of their /blog/# page, which linked to /blog/#/feed. The icon is not there in 5.0 - the /blog/#/feed still delivers the blog-specific feed, but there is no icon. Was this on purpose?

I was wondering if I could have Drupal.org 's sourcecode (all the modules that are being used here, the theme, database dump (no data, just structure)) etc so I could study some of it too. Is that possible ?

As i see template can be a set of blocks defined to show on page
when creating a node you can choose a template to show it
it can be also embedded to taxonomy module to select template all pages in category

is it good idea?

Something like:
