No, sadly plenty of your colleagues find it "normal", too. Sometimes I wonder whether you guys realise we can see you on the radar!
Usually this only happens on an ILS after being cleared to establish on the localiser only. Often with precise vectoring the localiser and GS capture occur simultaneously, so it's actually a bit of a PITA for everyone if we're forced to level off on the localiser because we couldn't get an established call in because of a busy frequency. You can also guarantee that the "cleared ILS" instruction usually includes a speed reduction, which is nigh on impossible when capturing from above.
On a non-precision calling established a tiny bit earlier (ie as the turn starts) just frees up capacity for the whole descent / timing / monitoring stuff.
