In the UK at least I think it depends on where. Undoubtedly at some airports expectation is that you "know" what you are doing however shaky you sound, at others you will get Fatherly attention.
However, I will say that most keep a pretty good eye on what you are getting up to, so if you end up departing from the procedure or clearly doing something stupid you will get a swift reaction, albeit from the sarcastic - "you were asked to report established" to "you appear to have passed through the G/S, what are your intentions".
Of course, don't rely on them get you out of trouble, far better to own up and in nearly every case you will then get all the Fathering you desire - if it goes horribly wrong at many places you will get a SAR or equivalent which is the least pressurised procedure on offer.
If the chips are down and you made it clear I suspect every where would give you gentle vectors onto the G/S and in fact with commercial traffic they are of course far more accustom to vectoring everyone - none of this procedure nonsense. If you want it slow and wide just ask to be positioned for a ten mile final!
Weather is often the cause of the shakes and never be worried about asking for a 10 degrees left (or whatever) for weather - you will get vectored around weather all you like and there is no excuse for bashing through obvious CBs and down pours assuming they are evident. Even CAT avoid this stuff if they can and you only need to listen to the director on the "right" days to pick up on the deviations for weather.
