Reference page 464 for 7110.65Y Change 1.
I was on the CTR for the PAATS# arrival. I can't have somebody doing a practice approach at PXT or any of the major fields on my freq while I'm holding 10/15 guys for the FNO. It's already bad enough for freq saturation when I try to hold 10/15 aircraft. This is only top of re-route/escape routes and coordinations necessary while keeping. This is definitely not acceptable and not doable. It only will
"help" the controller down the tube the lot quicker than anticipated. If you're a student pilot and trying to do practice approach, pick a non-busy day and field to do it.
