Please let me know what you think. Thanks for taking this, Warner. IMHO, persons reading UPDATING "after" causing boot issue would be in panic, and if they use pagers like more, less, or lv and cannot find helpful info at the top end of UPDATING, they would give up. So adding something like "All kernel modules are needed to be rebuilt when you update kernel. See note [1] in COMMON ITEMS section near the end of this file for details." as a top-side NOTE would be helpful. For [1] you updated at r367475, it would be better noting in what file to add PORTS_MODULES entry (/etc/src.conf, normally).
