I'm curious: what's the reason for it being the the average easiness?

Thinking about it, I'm guessing the reason is to try to adapt to the
user: a user who inputs lots of 'bad'/hard questions will have a deck
with a low average easiness, and so one should expect any future cards
to also be bad/hard, and so it's more efficient to set the beginning
easiness down low; while a user who inputs lots of bite-size 'easy'
cards will be quickly pushing cards up in easiness, increasing the
average, and thus one should expect more easy cards and so default to
higher easinesses.
