Pretty sure it's due to limitations in Max, at least up until OCIO support becomes available.

I believe they (3ds Max team)  added OCIO support in their roadmap somwhere in April 2020, God only knows how long long it will take them to finally launch it. There should be one more update this year so there is hope but I think it is more likely it will come with 2023 version.

Someone shared a Vray LUT on this thread that has really helped me a lot - not the same as full ACES support, but helpful.

Isn't Corona's wide gamut rgb pretty much as wide as acescg?
Isn't the ability to tone map the image however you like better than one fixed curve?

what is the expectation here?

I understand those that suddenly found themselves being a part of pipeline requiring aces but everybody else?

My only expectation is that colors don't get so saturated on hotspots. I believe that was part of the conversation here on this thread. For example, when the sun hits wood you get a yellowish halo around the white area. Yes, you can lower the overall saturation, but you're affecting the entire image. Reinhardt or crunching the whites don't seem to work as if you were working with an HDR. I may be wrong and I'm far from an expert in the subject.

desaturation might be a bit heavy but let me know how this one works for you. HC+lut.

mP_Reinhard2VRayAMPAS and mP_Reinhard2VRayFilmic have both been great to work with.

Do you have mP_Reinhard2VRayAMPAS_desatHL2.3dl as a .cube - I guess it doesn't matter for Corona Renderer VFB(?)

enjoy.
and in case this is not enough then FStorm desaturates highlights even more:

Awesome, is this the same as the hardcoded LUT that FStorm uses as a base?
