The updates and the theme-hacking are what drove me to migrate from wordpress to a static generator a month ago. I still had to do some hacking to get my non-vanilla posts to display right, but generally I found it way easier to hack on the generator templates than to dig into wordpress's crazy innards.
(This might just be due to WP having generations of cruft though - for me the hard part was always figuring out which arcane PHP method I needed to hook, and how WP wanted me to hook it, in order to add something to this or that part of the page.)
