often the result of one issue pressure groups or "regulators" with a personal barrow to push.
"Hello Pot this is kettle"........for you Dick and others
I did not see you on the distribution list Leadsled but I am sure they hade a preferential list for good folks like yourself that the rest of us were not on. There is not much to it you have not read on here already though.
Now onto serious things,
if it`s just VFR frequency monitoring above A045 then VFRs will be invisible to both sector and tower until they call the tower “prior to entry”
If they are above A045 the tower will not know about them because they do not have to report to anyone. The Tower is interested in them up to A045, above that its for the Centre folk to deal with....if you read that closely that means above the 4500' VFR will be invissible until radar is installed. Unless I am mistaken.
