Richard Bowker of the excelent green signals Youtube channel put much of the blame on the gov for pausing/cancelling the wires north of Wigton. This created the need for a unique 222 performance bi mode rather than a simpler emu.. what do forum members think? Would a straight 8xx emu be much better.

He is right in sense of making a non standard batch of trains, shortening the vehicles and trying to pack extra power into the reduced space was always a very high risk strategy.
Of course the alternative of taking wires further north, or cost of altering infrastructure to allow 15-25m platform extensions vs the cost of redesign (70% of the train) and retooling to build it and risk of this bodged design not actually working, or being years late, and requiring expensive lease extensions of 222s
805 are Bimode, but as discussed at length the carriages are to long to allow 2 x 5 car sets to be platformed at St Pancras.
With hindsight appears to be daft choice, especially as Waterloo suburban 10 car scheme had produced knowledge on how to move junctions, signals and lengthen platforms.
Roger Ford's long-ish read on the Cl810 in August does state that EMR probably still has the nuclear option of rejecting the entire fleet. Retaining that option may be part of the reason why EMR are not accepting new Cl810 until the existing ones have improved.
EMR have ended up being backed into a corner, they are continuing with what appears to be a failed design, because they have let the troubled fleet run beyond any contingency plan (without knowing if and when 810s will work, they have relinquished ongoing use of existing fleet), whereas they should have had a backstop date where an alternative was put into place (a replacement order, with extension of 222s until ready, or alternative solution). I am guessing there are dates in agreements (even if not public) where a nuclear handback option is still possible.
Maybe the 810s would have better future rebuilt as EMUs with bit of battery capacity the a diesel bimode
