As the maintainer of CoreJS (Denis Pushkarev) said:

Maintainers are the unsung heroes of the software world, pouring their hearts into creating vast amounts of value that often goes unappreciated. These unsung heroes perform critical work that enables all of modern technology to function – this is not an exaggeration. These tireless individuals dedicate themselves to writing new features, fixing bugs, answering user inquiries, improving documentation, and developing innovative new software, yet they receive almost no recognition for their efforts.
