I did used to love MagSafe, and initially was sceptical of it being removed. However, after thinking about it, even if it is a bit disappointing, it is understandable. MagSafe was introduced at a time when the first MacBook Pros had advertised battery life of 5.5 hours, and even then many reviews pegged it as 3-4 during normal use. Obviously, the laptop was to spend a lot of the time tethered to a wall socket, inevitably increasing the chances of accidents.
Now, MBPs have advertised battery life of 10 hours, enough for most full working days. Most people I know don't even take a charger with them if they're going out for the day any more. The iPhone, iPod, iPad etc. have never had MagSafe because charging overnight in a safe location sort of negates the need, and that is now what's possible with modern laptops.
Adding the benefits of switching to USB-C charging to this (charge from either left or right side, charging cables can be used with many other devices, less expensive to replace a broken cable), and you can see at least understand why Apple decided that charging through USB-C only was an acceptable proposition.
(I realise that there are a few flaws with this argument, namely the laptop with one of the best battery lives on the market - the MacBook Air - still ships with MagSafe. Maybe that was just to maintain compatibility with chargers on the other Apple laptops, as I'm sure if the MBA was introduced now, it would only have USB-C for charging. Who knows.
