Agreed. Magit in particular adds a steep learning curve to Git's.
I felt just the contrary. I would have never used hunk-based staging, cherry-picking, interactive rebasing (re-ordering, squashing, amending commits older than HEAD, etc) had I not come across Magit.
(It's so convenient that I can commit stuff to Org mode repo using Magit on my phone as ssh port is blocked at work.)
It's
good software and fun to use, but it's definitely not a good *general*
interface (which I'm assuming RMS meant).
