I do sort of see where you are coming from. However:
The days of the BAC 111, Trident etc are well and truly gone. Never flew those types but were friends with many who did. Flown all 737 types as well as slightly more exotic types like the awful buses, 777 and 757
The 737-200 I flew was not the same, but similar in approach performance as your 111 - in other words a brick. On the 200 you could 'get in' from an approach that on modern aircraft would be virtually impossible.
So these days flying to edge of a stable approach is something we do at all times in order to carry out a CDA.
You just cannot do the kind of approaches you did on the aircraft you flew because today's aircraft have a much lower drag factor.
