Unfortunately that comment referred to an IRC discussion that took place
last June on #whatwg.

IIRC, Hixie's position was that adding more explicit API for innerHTML is a
moral hazard because it encourages an anti-pattern. (Also IIRC), Anne and
Henri both sided with Hixie at the time and the DF.innerHTML got left in a

It's also worth pointing out that if it was decided to have innerHTML on DF
and on ShadowRoot, they would likely have subtly different semantics:

-DF.innerHTML would parse exactly the way <template>.innerHTML does (using
the 'implied context parsing).
-SR.innerHTML would use its host as the context element and the output
would be as if the input *had been* applied to <host>.innerHTML, then
lifted out and attached to the SR.

(I believe the later currently the case for ShadowRoot).
