Sorry, but I disagree here. I'm a regular user of tlmgr the package manager of tex-live and I appreciate the fact that it informs me of upgrade of itself and allows me to upgrade itself. (I'm not plainly satisfied that it forces me to do so...)

We are, more and more, evolving in a jungle of package managers (all using specific workflows for good reasons), I dream that one day, we will be able to simplify this landscape...

Personally, I use the os x system for updates + homebrew + tlmgr + opam + cabal + cpan + rubyGems + easy_install or pip +  firefox update system + emacs package system + eclipse + maven... Hard to even build the list of all the package manager one's use...
