Hi, I just wanted to express support for this feature, as a regular user who would have benefitted in the past. As an example, just recently my setup did not work as expected because of a bug now fixed in master. I was reluctant at first to recreate the source my distribution used to build Emacs. Had `describe-function' worked immediately I would have found the bug in two minutes; instead I ended up spending almost half an hour in total. Best wishes.
