It's never been an issue for me with my Zorki, or my Leica IIIf, which is also a 50mm FoV finder with no frame lines.
The only camera I'm aware of that has proper parallax compensation is Leica M. In those, the whole frame line rectangle moves to the bottom right as you focus closer. Everything else, at best, has additional marks to show you how much the shift is for closest focus, but you still have to estimate for anything in between. You can estimate the shift and slightly move the camera just before you take the shot, but if you're framing tightly, there's still the risk of cutting something off. The easiest way to deal with it is to frame a little wider to compensate, and crop later. For any viewfinder camera, framing isn't an exact science, and for most, there's a bit of guesstimation involved.
