> Any C++ code I have ever worked with is littered with `std::`. Replacing all that with `otherlib::` would be a herculean effort at best. You might be tempted to do a simple search and replace, but let's say there's also instances of `mystd::` (probably rare). Or perhaps you don't want _all_ `std::` to be replaced. Anyway, my point is that this whole ordeal gets hairy quickly. replacing a std::type by a semi-equivalent non-std::one has never taken more than a few minutes with my IDE's find-and-replace, on up to MLOC-codebases.
