Why wait container must starts at most 15 seconds after others？

[book987]

version: 3.0.7

We have a stuck node, as the logs shows, there's a huge gap between three containers' start time. I've search for related issue and pr, but looks like the 15 seconds limit still there, which mean we'll facing the same situation at new version.

Here I want to know why there is a 15 seconds limit? And why 15 seconds? Thanks!
