Good posts Dicky Baby.
All "good" VFR operators will be monitoring the appropriate Area VHF and thus note your arrival.
So when the frequencies are removed from the charts "for clarity"
How will the pilot know which frequency to monitor?
What frequency will a pilot give a Mayday or Pan call on? If it happens to be 126.7 Mhz will another pilot who hears this call be able to relay it to ATS if they do not know the correct frequency?
Using 121.5 mhz is hit and miss and also unrecorded so ATS and SAR agencies will not have replay capability.
