When you say it’s not a massive codebase, I’m curious, what are you comparing it to?

Splunk.

The previous poster was making out that in a year the code base would be a mess if people had done it.

This is a two-pizza team sized project, so it's not a project that the code quality would inevitably spiral out of control due to communication problems.

A single senior architect COULD have kept the code quality under control.
