Back in the day, I took some month-long vacations to places like Nepal that were really off the grid at the time. Some people I knew were incredulous that I did so. My actual managers didn't care because I did my best to pick "good" times to do so and did my best to inform people and make arrangements. It was never a problem.

I do think, over time, being more or less continuously in-touch became more normed.
