I agree with your overall sentiment Alan, two things sprang to mind from your latest post.
Firstly Clive Smith, a great angler and a Shakespeare man iirc who's death from bladder cancer prompted the link between Chrysoidine dye used on bronze maggots that were all the rage during the match fishing/river heydays and big weekly opens of the 80's.
Wasn't his home practice water Edgbaston Reservoir in Brum?
The second was the mention of the Trent...
Midweek and weekends would be booked solid around here with opens and now you're lucky (or unlucky, depending on your view) if you stumble upon a club match.
Blots on the landscape such as Burton Joyce and Hoveringham were almost household phrases and I'm not sure where the chain was broken because it's such a fantastic river these days albeit in a much different respect, the evenly spread shoals of Roach and Chub may not be the case anymore but anyone could win with a few decent Barbel which are widely spread, not to mention the big Bream shoals that thrive and get someone with the match fishing mind set of the likes of Ashurst or Marks on the river and they'd soon sort out a way to win off of most pegs.
I think the demise around here came in the mid to late 90's when the river was pronounced all but dead but the reality was it was simply going through a change, much like the water quality or should I say clarity, which is no coincidence.
Many have of course adapted to the change but once you break that momentum it's hard to get it back, especially these days when take up in angling is probably so much less and even less in the niche of match fishing > river match fishing.
I'd love to see it come back to it's former heydays in terms of matches and regularity but I doubt I ever will, the consolation there is that one's loss is another's gain...
For me at least
As much as I aspired to the match fishing heroes of my youth and tried to emulate them the fact of the matter is that I was all but, in that particular discipline...
Rubbish!
