Great news!

As I just mentioned in replying to your last mail, for the monorepo
conversion, I would say the week beginning Monday, November 29th 2021.
Rampdown is due to happen the Friday before:

Assuming the git versions can be different again and retain
the jdk8u & jdk8u-dev names for consistency with later versions
(i.e. github.com/openjdk/jdk8u & github.com/openjdk/jdk8u-dev),
I would suggest just using a "mono" prefix i.e.
jdk8u/monojdk8u & jdk8u/monojdk8u-dev as these are only going
to be in active use for <6 months.

But I'm open to better suggestions :-)
