4.4.1 Vibration change on N5?

Ok, I know this seems pedantic, and over analytical, but I've just updated my Nexus 5, and the vibration feels different. Much tighter and shorter, just like the Nexus S was.

Not sure if I prefer it, I liked the previous vibration when using the phone. Using the keyboard, or pressing the on screen buttons had a nice feedback, now it's just a little too sharp and strong for my liking. Though I do believe this is an improvement for notifications, as the old style was weak for that.

Is this a necessary change? Or could they have improved notification vibration, without changing it's interactionary behaviour?
