No. The problems 'were' POOR DESIGN. Good design means installation is easy and safe. Another circular argument, when not getting points made. You sound like someone carping about losing a skill because of deskilling. Sounds like plumbers who whined when copper came along because their lead joint wiping skills were no longer needed.
I always admired the simplicity and economy of rings and all those I knew at the time thought they were superb. They eliminate many radial circuits. We always defended them.
I looked at the bad points of rings and considered how to eliminate them.
1. Ring being broken then splitting into two radials off the one 32A MCB then 2.5mm cable protected by an MCB that is too big creating a fire risk.
Solution?
Up the cable to 4mm.
2. Ring's heavy current not running through the cable, being run through the terminals at the rear of a socket. Potential bad connection at the rear of the socket due to stressed cables. Until 'recently' this was difficult to eliminate.
Solution?
Screwless connectors in backboxes now make it possible to have ring's current not run through socket terminals.
3. Ring out of balance with too much current on one leg, which could be a fire risk using 2.5mm cable.
Solution?
a) Connect leg 1) of ring to sockets 1, 3, 5, etc. Connect leg 2) to sockets 2, 4, 6, etc.
b) Use 4mm cable.
Other points that apply to rings and radials:
1. Conductors bunching under stress being forced out of terminals at rear of sockets in packed backboxes.
Solution?
Use lever screwless connectors in backboxes to take the cable's current load, with a flex from the lever screwless connectors to the sockets terminals. No stress on sockets terminal with socket moving into position with ease.
2. Arcing due to lose screwed terminals.
Solution?
a) Use screwless connectors, as terminals do not work loose.
b) Use an AFDD to isolate circuit if arcing detected.
The ring using screwless connectors, ensuring circuit's current runs through the cable and protected by an AFDD is now near bombproof. All we need is screwless connectors in the rear of sockets (available but limited) and on MCB/RCBO/AFDDs (available on the Continent, but can be imported). Then no many needless expensive circuits.
Note: if you think screwed terminals only loosen after a DIYer had screwed it up, you must not have been around too much.
