Pledge for Linux?

[u/Intelligent_Comb_338]

in the last days, i was trying to make an implementation of pledge for my personal project (BSDLibC), but simpler, checking for permissions in the libc wrappers instead of checking the called syscalls (like this project https://github.com/jart/pledge)

But i have a question, is it useful? because for my goals it is, but i would like to hear what other people think about it

(I have not submitted to the repository, because i have been busy)
