You have a day or two, and I hope this should be enough for adding new
features.  (If they have still some rough edges, that could be fixed
later on.)

So I suggest you install that ASAP.

I agree that having compatible options makes sense, provided that
changes in ruby-mode that affect existing/default indentation style
and font-lock are relatively safe.

It's up to you.  If the above-mentioned method suits you, we can have
that on the release branch.
