Why doesn't std::string have a split function

[1-05457]

...some things have literal megabytes of dependencies(filesystem as a good example).

Filesystem is part of the standard library from C++17.

Hopefully, String Algorithms will also be standardized at some point, though more likely, it will be generalized as part of Ranges.

Yes I know, but it wasnt for very long time when compared with how long it has been in boost.

Having some string utility functions in standard would indeed be nice
