IVT protection provider status and IVT trusted server access for companies offering both ad tech and IVT detection

[acomets]

The section about Post-bid IVT models suggests adding another trusted server for IVT detection providers and introducing the IVT trusted server API, which would be open only to a list of IVT detection providers controlled by the browsers.

How would companies that provide both ad buying and targeting technology and IVT detection/prevention solutions be treated in this regard? Would they still be able to access this server/query this API to run their post-bid IVT detection models over the decrypted events?
