Why <Session as Drop>::drop emits warnings?

[qryxip]

When a Session is completely dropped, it emits two WARN messages.

Is there any specific reason why the level is not INFO or DEBUG? I git-blamed the part but couldn't realize.

ort/src/session/mod.rs

Lines 524 to 531 in 2fdba8f

	fn drop(&mut self) {
	tracing::warn!("dropping SharedSessionInner");
	if !self.session_ptr.is_null() {
	tracing::warn!("dropping session ptr");
	ortsys![unsafe ReleaseSession(self.session_ptr)];
	}
	self.session_ptr = std::ptr::null_mut();
	}
