On Android phones. iPhone doesn’t have this privacy deficiency.
Regardless, MDM installed app visibility is limited to those users who opt-in to an organization managing their personal device, and isn't an effective way to broadly gather what apps a given person has installed. What's described in this post would work on any user/device, and there's no way to deny/opt-out of specific permissions.

Fun fact from the MDM implementation - the most private way (at least to the company policies) to have a company-connected device is to buy a separate phone and install company's MDM on it. On company provided devices, the company may locate company's assets at any time but doing so on a personal device is a privacy breach.
The reason is that Apple demands that the UPN (the account ID) and the email address are the same. For us this is not the case (our UPN is our employee number as an email address, whereas our email address is just our name). And obviously we're not going to change this for ten thousand users because Apple wants to (most of which don't have Apple devices because we're a European company). Also, you have to manually decide what happens to each user that has already created an account with their corporate email address and what to do with the content they purchased on it. This is not feasible for a large corp. We have commented this to our Apple account manager for years and years but they simply don't care. If you work in this realm you probably know that Apple doesn't really care about things that matter for their corporate customers anyway. The consumer is their main client and it shows (unlike with Microsoft where it's the opposite).
So the whole account-driven enrolment (User Enrolment) as well as everything else depending on managed Apple IDs like DEP for Macs is completely out of the window.
The problem in my opinion is that I as an admin can simply query for example all the employees that have something like Grindr installed. Considering the current political climate in the US (or worse, the middle east where this can lead to a death sentence in some cases) it's obvious why this is super bad. And really, why should we be able to do this at all?
The bad part of this is that apps have to specifically support the multiple profiles option, otherwise they can't be used for this.
And yes, I agree, that is the best way. We have the same restrictions for personal devices. Though I as an admin know we never use the locate functionality (and I know every person who has access to it).
Android has this really well worked out with their work profile. It's like having a company VM on your phone. Really great separation.
But on Apple we can't use a similar option which I admit does exist, but there's too many strings attached (see the discussion above).
Account driven MDM enrolment pushes the Pareto front when it comes to privacy/conveniency compromises from my point of view. I will ask my IT if they have already looked at it.
If you have the self control to refuse to ever check Slack and disable all notifications/etc on your personal phone when not on call, this doesn’t apply as much. But for me I default to trying to stay on things and forcing myself to disconnect is a net good, even if it does mean I carry two phones at times. My pockets are large.
