I'm not sure it would be viable. You need sharp edged sockets because the wire cold welds to the socket pin and if you unravel you can feel it pop loose from the corners. "Gas tight connection" as they called it. You can wrap round analog component pins but it doesn't stick as well. So you're mostly limited to digital DIP components in sockets. Given that limitation it worked very well back when "The TTL cookbook" from the late 70s was mostly contemporary.
Counter intuitively people assume short neat wiring is lower capacitance therefore better, actually complete rats nest has lower capacitance and lower coupling. You aren't going to be running much above maybe 20 MHz but that was OK in the days when a 2 MHz nmos Z80 was "pretty fast".
Everyone does something dumb once like wrap an entire 8-bit microprocessor system using the same wiring color, but back then it was easy to get multiple colors and do your data bus in green and address bus in red or whatever.
Another anecdote back in the old, old days original "TTL", no series like LS or HC, was kinda power hungry and 30 gauge wire is not thick and people would daisy chain from power pin to power pin and 20 hungry chips later be perturbed that 5 volts comes in but there's only 4 volts at the power pins of the last chip. Lots of people hand soldered larger gauge wire for power and ground along with hand soldering on decoupling capacitors.
Another anecdote from the ancient days WRT cross coupling and interference the electrical noise a circuit generates is almost solely proportional to risetime / falltime of gate which depends on gate family not clock speed. So a 10 MHz plain TTL board was much more electrically quiet than a 0.89 MHz "quarter colorburst crystal" circuit made with "F" family chips, this is very counter intuitive to many people.
What a color burst crystal is, and why they were so cheap until the 00s or so, is beyond the scope of this post LOL.
Nothing forces people to learn RF/analog electronics as well as trying to do fast digital electronics.
