It is still possible to use POSIX profile with modern versions of Vala, have a look at this project: 
https://github.com/radare/posixvala

But there are some GLib features that can't be implemented with POSIX profile: abstract classes, interfaces, 
async methods, non-compact classes, regular expressions.
