Yes, window managers in general like to think they have control over where windows are placed.
Implementing this feature would mean storing window coordinates and size after shutdown which would have to be restored. Storing part is farily trivial, the problem is that you cannot guarantee at all that your windows ends up where you want.
Most WMs I’ve dealt with simply don’t care because they are configured to place new windows where it thinks the “best place” is, even if the application says otherwise. Then of course, tiled WMs are extremely strict and you cannot even assume you get the same window size … You can try to make lots of workarounds to get it as good as you can, but then the feature is suddently very complex and hacky.
Then there’s the off-chance that with multimonitor support you might end up with coordinates that make no sense at all if monitors have been added and/or removed in-between sessions. This adds complexity as well.
Then of course there is the issue of having to implement it for all drivers (on PC).
