I'm all for it! The fact that there's no need to use third-party programs is a definite plus, and a significant one at that. If such functionality were available in HD, I wouldn't even consider using anything else. And I assume it would be more convenient functionally.

Ideally, I think the information obtained from the scouting should be available until the start of the next turn. Then you could calmly study the scouting during the opponent's turn, and no screenshots would be needed. There would be no need to stitch fragments together, overlay (combine) ground and air scouting, etc. No need for any complicated procedures – everything would be available to everyone within the game itself. And to prevent the grid from bothering anyone, you could make it so that if the grid is enabled on the map, it would also be on the scouting. And if the grid is disabled on the map, the scouting would also be without a grid. In my opinion, that would be ideal.

Although, the ability to export the scouting of an entire area (if that's what we're talking about) in a decent resolution would also be a useful addition. Firstly, in case a game is saved, it would allow you to study the scouting again without any screenshots or other workarounds. And secondly, it would allow you to view an old scouting, but without incurring new mana costs.
