Yep, I know what you're saying. In the 'ideal' world then there's no problem going to minimums, but as you say some people will try and salvage the approach by overcorrecting. The thing to remember is that when FSD is reached and / or minimums, a missed approach is called for...no question...As people have already suggested, its wise to apply your own personal minimums, to whatever you feel happy with.
SY, On the subject of 'VFR ontop', there is an exception in the ANO basically saying that if you hold an IMC rating then the 'in sight of surface' bit is no longer applicable [as BW already mentioned]
