Agreed. Printer manufacturers are coming up with their own quality assurance solutions like EOS.

EOSTATE MeltPool observes the light emitted by the melt pool. Key elements are two photodiodes located on- and off-axis, a camera adapter, a specialized signal amplifier and according spectral filters to separate process light from reflected laser light. EOSTATE MeltPool software offers automatic data error correction and real-time process visualization and evaluation. For data analysis, the EOSTATE MeltPool Analysis Toolbox visualizes data in 2D or 3D mappings and enables the evaluation of indication clusters. The tool works based on three advanced algorithms to obtain different data interpretations.

From the collected data conclusions for the resulting quality in the final part can be drawn. Customers define corresponding parameters (MPM Parameters) using the open and flexible EOSTATE MeltPool Analysis Toolbox and can set their thresholds in alignment with their particular quality requirements. Live monitoring during the build process of a real part helps to automatically identify error indications based on these MPM parameters. As such, EOSTATE MeltPool is a powerful tool for quality-oriented work in Additive Manufacturing.

The reason I believe SGLB still has a big leg up is because Spartacus3D decided to utilize PrintRite3D in their EOS machine for quality assurance as opposed to the solution that EOS offers.
I'm betting that it's because their solution has been in test and evaluation mode for a few years now and manufacturers trust those results. Competition is coming but they'll need to have their quality assurance solutions vetted by the Big Boys as well to verify the accuracy of thee results. They next piece to the puzzle is the whole third party validation as Silversmith discussed. The FAA will require this.

4. THIRD PARTY CERTIFICATION BODY. In
addition to administering the qualification program in
accordance with this AC, a third party certification body
must assure that the manufacturer provides and
maintains a quality control system in accordance with
FAA-STD-013, Quality Control Program Requirements,
or suitable alternative, such as the ISO 9000 family of
standards or Department of Defense quality standards. It
must also assure that testing laboratories that perform
qualification testing conform to the requirements of the
International Organization for Standardization/
International Electrotechnical Commission (ISO/IEC)
Guide 17025, “General Requirements for the
Competence of Testing and Testing Laboratories.”

I got this from a FAA circular for a Airport Lighting Certification Program now imagine the certification required for aerospace parts.
Update to message. I just found airbus quality assurance general requirements.
They require third party

For non-destructive testing processes, the process must be qualified in compliance with
European Regulation (see requirements for Human Resources monitoring).
? All the NDT procedures (process sheets) must be validated by a level 3 Cofrend Cosac
agent.
If the company does not possess internal level 3 personnel, validation can be
subcontracted to a Cofrend Cosac approved organization. In case of critical part, this must
be approved by ECG-ECE.
? In the case of processes where operators qualification requires a third party organization
(welding and NDT in particular), the subcontractor must provide with qualification
evidences granted by these organizations.
? If these organizations are not qualified in compliance with European Regulation, an
equivalence with reference organizations must be demonstrated.
