I thought it was the default too but now I'm thinking I've just been conditioned into accepting it as a sensible default* and might have automatically enabled it on my own accord after reading the instructions.
Of course I like to poke around a new system and reconfigure everything only to immediately forget I made that change.
I started using full drive encryption as soon as I started getting faster devices (i.e., not the Nexus 4) - in fact I've only not too long ago reformatted an external backup HDD (WD Green - unremarkable) to use LUKS encryption, and haven't really noticed a noticeable performance hit (Phoronix has some good benchmarks on various types of disk/folder encryption). It's laughable now to think I left it on the floor ("secured" by the 5-pin tumbler lock in my front door) without any kind of data/identity theft* protection for so long.
* As an aside, here's a vaguely-relevant #1 trending story in Australian media for the past few days (related in a general security sense which most people neglect - not necessarily disk encryption): https://www.smh.com.au/business/companies/masterchef-finalis...
