Excellent. The fact that you compile from sources makes the things
easier. I guess we can add new collations officially into 10.2.
Then after 3 month if you'll feel that 10.2 is not mature enough
for you, we can make a custom non-official 10.1 tree with the new
collations back-ported (it should be trivial to do).

Thanks. Then we're flexible to implement #2 first, and wait for #1
to be done under terms of Google Summer Of Code 2016.
