I’ve mainly handled it by pushing my team to be extremely conservative about what dependencies we take, especially if they pull in scads and scads of transitive dependencies.

This elegantly mitigates three problems in one go: update churn, dependency hell, and supply chain attack surface.

It also, frankly, tends to make the code easier to understand. I’m not a huge NIH person but I do have to say that a lot of packages these days tend to encourage ways of doing things that are unnecessarily complex. More than once I’ve replaced a dependency with homegrown code and reduced LOC in the same commit.
