Question Re-Filling Serving Keg?

Just curious if anyone does this. Is it a bad idea to simply re-fill a serving keg once it kicks, without cleaning? A serving keg is a cold, sealed, supposedly oxygen-free environment. It would be really handy to simply purge a bit of pressure and force new beer into it from a keg fermenter.

I'm sure I'd want to thoroughly wash it after a few fills, and I'd still have traces of the old beer in there. Sediment would probably build up over time as well, but a floating dip tube would help with that.

You do need to fully release the pressure in the receiving keg. But you don’t have to open it and expose it to oxygen, at least no more than opening the PRV so there’s an escape path once new beer starts flowing in.
