Do ZF gearboxes no longer come as an option and if they do, can they come with stop / start?

Yes these are ( Irritatingly ) fitted with Voith D854.6's to be exact, Arriva's standard spec now. Completely unsuitable for the work there being put on, They seem to top out at the rev limiter first before the Speed limiter, Which is another bug for me.

ZF do still come as a option, Speculation is buyer's arnt specking Ecolife's due to not being compatible with Cummins Stop-Start feature, But I disagree as ZF have been offering the Ecolife with Stop-Start compatibility since 2015 for up to 1600nm of Torque, These coming in at 1100-1200nm should be a cosy fit. Id hint it's a money saving decision.

A rather boring fact is that this batch suld come with a extra 100nm of Low End Torque to help fill the gap of slow acceleration from a standstill, Though it is barely noticeable due to how Voith's work in 1st Gear, And how ADL Tune the things down for more MPG, This is commonplace for all Cummins offerings from 2017 so is expected to be on all Cummins fitted buses from this year.
