Hello, thanks for this great contribution!

Title says it all, is this package abandoned? Are you looking for maintainers?

This is a great contribution to the PHP community, I miss updates here and I feel it would be a great loss to the community if a project like this dies. Although we have plenty of Worker handling implemented as extensions, a native PHP solution is always important as its transparency will always make some things easier and more accessible than an extension written in a different language.
