“2. Some sources to this day assert that some problems—moderate?—were averted by a huge amount of work ahead of time.”

For Y2K?

Absolutely.
Things would have been a disaster had nothing been done, but we had skilled people doing a lot of work to fix things ahead of time.
I worked for a dot com at the time.
Seeing how skilled the people were in the industry; I wasn’t very worried about Y2K.

THANKS FOR THE CONFIRMATION of that point.
