The cost of having PCBs made has dropped significantly over the last
20 years or so.  Back when those 3M parts made sense the cost of
having a double sided through-hole PCB made were high enough that not
many folks could splash the cash on having multiple PCB spins for
low-volume circuits.  Nowadays you can get a double-sided board
manufactured for less than the parts cost in building a prototype.

Here's a fun site to play games on: https://pcbshopper.com/
For example, 100mm x 80mm double-sided board, cheapest options,
shipped to the USA.  JLCPCB will send you 5 of those boards in 6 days
for $19.  So what if you have to respin it, save yourself a couple of
Starbucks "coffees" and respin it.
