I have heard that Microsoft do intend to develop and introduce this feature at a later date for commercial customers via the standard Phone System and Call Plans; however it's not currently on the Microsoft 365 road map.
Yes - I understand completely. The point is that it is possible today to use Microsoft Teams for compliant call recording in the Direct Routing scenario. However, most organisations want to see it within Microsoft's phone system so they don't have to have Direct Routing. They want, as you say, all in one.
So it will be some time before this comes in. As Adam says, the uservoice will help but it is known that Microsoft have compliant call recording on their radar and hopefully this will be sooner rather than later. Some organisations are holding off on voice because of this. It was a big reason why many companies didn't go all in on Skype for Business.
