Presumably, Mullenweg aimed to end that sentence with something like “SSL is necessary for additional functionality and greater security”.
At any rate, this is a good move. WordPress powers an inordinately high percentage of the web — something like one in four websites is built on WordPress. Between their encouragement and nudges from Google and Apple, it’s time that the web became more secure.
On that note, I plan on making HTTPS mandatory for Pixel Envy over the winter break, when I have some time to make sure nothing goes awry.
