Long recoil semi automatics What happened ?

The first and debatable the best the old A5 long recoil and all the spin offs from Italy America Russia other European country’s and Japan. Why did the fall from favour, in what is a very reliable mechanism which will function for a long time with minimum fuss and trouble.
Why are they no more, WHAT HAPPENED?

Well with the exception of a couple of posts the Reaction because that is what it is a reaction is what i expected.
But touched on above is the Franchi 48AL which as pointed out is AFAIK still in production and right at the top of the heap in Upland semi autos.
Obsolete is a far too damning word i feel, it implies it has been out performed superseded dominated made pointless, which is simply not true.
Others have come this way gas short recoil inertia various types of gas system but in essence non do anything the Original A5 was not doing nearly 120 years ago.
Much is made of the Benelli and Browning inertia systems on the New A5s how they are clean function for long periods without issues, all relevant but the Original long recoil did it just the same.
Bredas A5s Franchi 48s SKBs Baikal tulla many more made good reliable long recoil guns which looked less Hump backed than the A5 and the Remington 48 mirrors this with others from the states, so good looking long recoilers could be produced today virtually identical style wise to the equivalent gas autos.
Gas systems can regulate to some extent but so can long recoil actions anyone who has used magnum franchis and A5s with lighter loads for duck or dove will give clear testimony to this.
A history lesson on what happened is in the thread already the 1100 Remy did come along and the Long Recoil as almost sounded its last post, But my question is still! WHY?.
They are not out classed any more than Benellis inertia system is, I can think of may i know who would buy a long recoil semi today if they existed, a Long recoil 10ga to Replace the Ithaca Mag ten SP10 that recently passed quietly away with few so much as blinking an eye never mind shedding a tear.
As magnums long recoils are good ask and A5 magnum user or Franchi 48 mag or Breda magnum user.
As upland guns the Franchi 48AL 20s and 28s are an awesome if not superior shotgun so to all intents and purpose WHY? Why not new long recoil semis.
I very much doubt any manufacturers will re adopt the Long recoil system anytime soon, but i for one feel this system gives up nothing to any of the other systems in form and function, and in down and out reliability durability and easy maintenance its 120 year age leaves it old fashioned perhaps but never outclassed or out performed.

Please forgive me i am not a Engineer and do not understand the build process of say the old A5 i know it had screws and lock screws was incredibly well made, but simpler typicaly moder constructed semi autos with long recoil were are produced, a Remington 48 is pretty much an 1100 reciever style trigger group, with the exeption of the gas system rather than bushes and spring, i as a layman do not see where the extra cost of long recoil lays, the barrel band is simpler on machining than say the gas chamber and porting of a 1100 for example.
Could be something i have missed regarding the costing aspects but i did say i am a layman re Engineering proses.

I do not feel the gas auto is more reliable, It will not run as long as a set up long recoil gun without maintenance.
Long recoils will shoot thousands of rounds without issue no gas auto can boast that, not even the versamax they will need maintenance before a Long recoil will.
