alt Hacker News> We have something in-house designed for our use cases, use that instead of the standard lib equivalent
Yea, you encounter this a lot at companies with very old codebases. Don't use "chrono" because we have our own date/time types that were made before chrono even existed. Don't use standard library containers because we have our own containers that date back to before the STL was even stable.
I wonder how many of these (or the Google style guide rules) would make sense for a project starting today from a blank .cpp file. Probably not many of them.

... and for many of those blank .cpp file projects, the style guide should probably just read "start a blank .rs file instead."

The STL makes you pay for ABI stability no matter if you want it or not. For some use cases this doesn't matter, and there are some "proven" parts of the STL that need a lot of justification for substitution, yada yada std::vector and std::string.
But it's not uncommon to see unordered_map substituted with, say, sparsehash or robin_map, and in C++ libraries creating interfaces that allow for API-compatible alternatives to use of the STL is considered polite, if not necessarily ubiquitous.
