It makes sense on a residential are when building new infrastructure.
Personally I rather be on the ground working on a pad mount transformer than in a bucket truck working on a can.

This is a really old combination of parts.
As long as your under 5000 volts it’s relatively easy to do cable termination.
This is not a 5000 volt installation, and it was not really done to todays standards.
But consider the costs involved in having all the parts and fuses in metal clad enclosers on the ground in switchyards, fences barb wire to keep people out…
Your hydro rates would be higher to reflect the extra parts and steps required to electrify your neighbourhood compared to a pole top system
