We didn't had nodejs for a long time in fedora, because it used to
bundle a lot of code from other projects.
The other issue is, that is a quite fast moving project. When you want a
stable platform, you probably don't want to update every two to four
weeks to a newer minor-version, and probably want to avoid new major
versions at all.

So, it ended up in: we compiled LESS code offline and combined that with
the package. That is not ideal at all for folks changing the style to
give their dashboard another look. I assume, that's a pretty common

Exactly, just compare the binary size with the size of less sourcecode
in horizon sourcecode at all.

So, that being said, dropping lesscss in favor of re-integrating node.js
is a big step backwards. If there's something missing in lesscpy, we
should fix that.
