The OS-independent GNU API is in my mind an issue of documentation,
describing which APIs are Linux-specific and which are not.
I would be happy to see gettid implemented as a wrapper if someone
would step up to document exactly how it behaves and where it is valid
to use the resulting return value and in what APIs. That I think is
where everyone balks at the work.
