True, but at the moment we're just interested in getting Orego to play
ANY joseki, i.e., a reasonable move in some corner, rather than a
disastrous tenuki. Finding the "right" joseki will be future work.
(Orego also has a small fuseki book, which we're working to expand.)
On an intermediate level, a joseki that is good for a professional is
not necessarily so good for a kyu player. Professionals are better than
weak players at using thickness, whereas solid territory is worth much
the same to both. So if your objective is for Orego to become 1-dan,
you should tend to prefer josekis which give low solid territorial
positions, leaving the hard-to-use outer influence for its opponents.
Good advice!

By playing/watching bots on kgs I've noticed a bot specific weakness in
applying OB on 19*19.
There is a consistency gap from OB to post-OB.
And ironically it's worse for simple and safe joseki than for more
extravagant, influence-oriented ones.
When "pure" MCTS kicks in, the bot will go for what remains of center
influence, trampling on his own low positions.
Alleviating this problem is even more important than direction of play or
than the local quality of the move.
For example, MFoG likes to play keima boshi on a low hoshi kakari, even when
it doesn't have any extensions.
This is a wise choice, considering current post-OB play.
One day, when MCTS becomes more refined, bots will stop overestimating the
value of influence.
But until then, it is better to use an OB that puts the bot in a position
that it likes, than in a position that is "objectively" good.
