I don't think it would be wise to include them now in the upcoming
release. Too many things would need to be re-tested and could go wrong.
However, please feel free to add them now to the development version so
that we don't face that problem again in about 5 months.

This is marked as deprecated, but still included. It should stay that
way, and should be removed in the current development version now.

Same applies here.

I marked them now in the release branch. To be gone by the next release
(meaning now in the development version).

This (including a lot of the stuff we agreed on to remove) is not ideal,
but it didn't pose problems while testing, but could if we now remove
it from the release. Let's phase them out the gentle way. I don't see
harm done by doing so.
