Your position is certainly not unusual in terms of how businesses are currently assessing future travel requirements, and you're absolutely right that in more recent times, many (especially First Class long distance) carriages have become extensions of the office. That's actually one of the reasons that I particularly dislike complimentary at-seat dining, and the fact that it tends to be dumped on the passenger in parsimonious portions at times to suit the operator and/or staff, rather than the time of day or passenger preferences.
However, and in future, particularly if you take into account the reported quote above from GWR, the operators may need to review their offer just as much as businesses are reviewing their requirements.
This could, for the likes of GWR, LNER, Avanti etc., especially, mean that they have no choice but to look to the leisure market and assess what rail can offer that other modes can't. Whether that's speed, flexibility or, in this case, on board experience, there's a thought that on board catering could actually be both a marketing and a revenue opportunity. The railway is very much behind the curve in this regard; it pays little to no attention to the additional revenue opportunities available to it, and these opportunities aren't 'punts'; they're ones that other travel operators have been benefitting from for years. Indeed, it's possible that some of those companies may have taken the ideas from ones that BR itself was involved in for years.....
