The industry is moving away from the client library approach. This is possible in a place like Google where they force folks to write software in one of four languages (C++, Java, Go, Python) but doesn't scale to a broader ecosystem.

It sure scales, I am yet to work in organisations where everything goes.

There are a set of sanctioned languages and that is about it.

The subtle aspect of the comment you're replying to is that _they write everything_.

Hard to cram a new library into some closed source vendor app.

Depends how it was written and made extensible.
