Automatic hyphenation on the web has been possible since 2011 [1] and is now broadly supported [2]. Safari, Firefox and Internet Explorer 9 upwards support automatic hyphenation, as does Chrome on Android and MacOS (but not yet on Windows or Linux [3]).
Via inks [4], “All you need to know about hypenation in CSS (Cascading Style Sheet) | Clagnut by Richard Rutter [5]”
I had no idea that hyphenation has been supported for eight years now. And adding support was easy enough—I already mark the blog as being English so the only remaining bit was adding the bit of CSS to enable it. I've been manually (for various values of “manual”) hyphenation hints with the use of ­, such as when I mention FaceGoogleLinkedMyBookPlusInSpace or when I do my XXXXXXXXXXXXX XXXXXXXXXXX XXXXXXX censor bars.
Now, it looks like I don't have to do that anymore. Sweet!
