That is precisely my view. The trains are here, and nobody is likely to stop the whole programme for tables, armrests, power outlets etc., the stakes are just too politically high.
For the record, I can understand that some have issues with their comfort on the trains, but the order is just too big and the delivery too intensive to halt, what with the impending completion of London Bridge, the readiness of the Canal Tunnels and the need for the very high capacity that the trains bring to the network.
So repeated complaining to the TOC, who does not have a responsibility for the fitment of the trains, won't make any difference. Maybe when the deliveries are completed and full services are operating a more rational assessment may be taken. My guess would be that such work could be scheduled by temporarily removing any non-core services from class 700 duties allowing a few trains at a time to be sent away for some modifications. The hire of their replacements would of course, need to be paid for and despite the Thameslink routes being amongst the most profitable in the UK, the unbudgeted cost might be enough for the Dft (or their successor) to see it a too difficult, and extend any 'promises' about the likely timetable.
The next opportunity might then be the mid-life refit, which in material, labour and budgetary terms, would probably be possible within the scope of the budget. Hence my comments that any Twitter postings, especially from TOC staff, probably have little relation to the true state of decision-making on the matter.
