Sometimes, convenience means sloppiness.
Easy deployment can sometimes mean you don't actually look at a feature, or you don't run the tests because "that couldn't possibly have broken anything". The net result is that you deploy something thoroughly broken.
Case in point: one of my projects uses Lighthouse for defect tracking. It's generally a good little system - ASP-hosted, written in Ruby on Rails, quite simple. ..... And about once a month, someone deploys something totally broken. The entire site is down for anywhere from 15 minutes to 3 hours.
So use the tools that make deployment easy, but keep asking yourself if it's too easy - and don't let easy become sloppy.
