What is the problem this feature will solve?

Prevents other processes from opening a file or device if they request delete, read, or write access.

windows: https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-createfilea
also in unix: https://man7.org/linux/man-pages/man2/flock.2.html

so it should be consider as a well-supported API, yet node (native api) doesn't implemented.

What is the feature you are proposing to solve the problem?

add a api like fd.lock() or fs.lock(fd)

What alternatives have you considered?

outdated package like https://github.com/baudehlo/node-fs-ext

Duplicate of #49256, #122 (from 2014!) and probably many others. Long story short: not going to happen because irredeemably unsafe and irreparably broken. Read through the linked issues for more details and discussion.
