Standard Noise:
I agree with almost everything you say, apart from:
"BTW, brain fade, that explains why we sometimes ask the inbound if they are visual, and if they say yes, then we taxy you forward to G1 and explain to the inbound that they may get G/P fluctuations due to your prescence at G1. "
As someone who operates on both sides of the gulf that seems to have opened up on this subject, I would argue that once I am visual with the runway and/or the PAPIs, then glidepath fluctuations are irrelevant, as I am using the eyeball and not the ILS to judge my flightpath. Thus I would suggest that your explanation to the inbound might be superfluous, but no more so than a call to report at a holding point which is visible to the Tower!
1-1 then...?!
