What MDM specifically? It would be up to the MDM version to be consistent with how they display and handle the SW version. Stuff like AutoPKG and Munki should be able to handle it just fine.
I use both AirWatch (now VMWare Workspace ONE) and MS Intune (now Microsoft Endpoint Manager) right now.
The problem is that they incorporate different technologies. For example, Workspace ONE includes Munki for its app distribution but MS does a different thing. Also many run scripts in the background to check things, which may or may not do things differently.
I haven't really tested Big Sur much with the MDMs because there isn't much point until all our antivirus software etc is updated to support it. But I'm pretty sure this will cause additional issues, and Macs in enterprise are already very difficult. Mainly because of Apple's consumer focus, enterprise manageability is always second place unfortunately.
I'm aware those aren't MDMs, however they still will have to deal with this. I was also under the impression that Intune didn't really support software management for macOS. I think Jamf and WS1 will be just fine. I think the Kernel extensions are going to be a much bigger problem for those of us managing Macs at scale with things such as Antivirus software like you said.
