Git git git

Why is Git for some only the one perfect DVCS and no discussion is possible? From Git is the only DVCS caring about performance incl outdated benchmarks, to the ‘all DVCS’ systems are hard’ and lastly ‘switching VCS systems is easy’. Regarding the latter, who is going to do the conversion? I am fully willing to do Bazaar (perhaps Mercurial.. I’d first would have to investigate that). But Git? Even a ‘am I capable?’ would dismiss me from doing that. Anyway, from following the stuff before the CVS->SVN switch, to fixing loads of things afterwards, switching a VCS system not at all as easy as some make it out to be. Just the under estimation makes me worry.
When I see something which is broken, I cannot just leave it without trying to fix it (aside from lacking time and if I am able to, but ‘able’ is pretty easy with root access). From DNS stuff, to LDAP, accounts process (Mango), SVN repos creation, etc. Although I’d really love if more GNOME sysadmins would be active… anyway, if Git is considered to be the only option and the attitude regarding the ease of switching stays the same, I do not want to have the ability to fix whatever was forgotten or broken.
