Yep.
For GNOME their are packages available for DevHelp through third parties (e.g. Archlinux->AUR). DevHelp could make good use of a direct installation option for users.

I wish Zeal made it easier to inject custom CSS based on the current docset (like Stylus in a browser lets you inject different CSS per domain), or change the zoom level independently for each docset. One pet peeve of mine is fonts I dislike or find too small/large, and browsers currently have better tools for customizing reading.
The supplied C++ docset comes from cppreference.com and is very, very useful to have to hand.
The Python and CMake docsets are also particularly useful to me.
