We had this a few years back in a Victorian house that had a very awkwardly shaped kitchen.....
It was also a very tiny room, although it did have a large walk-in larder/pantry off the kitchen and a conservatory (added by a PO) that we utilised as a breakfast room with scrubbed pine table and additional storage, as well as housing the washing machine and a second sink in a utility area.
The kitchen itself - with three doors, one window and a cut-off corner - was only about 8' x 8' and originally had a floor-standing boiler, that we replaced with a wall-mounted one freeing up a little more space. We had a 6' pine dresser along one wall, a custom built butler sink unit with drainer to one side and cupboards under in front of the window, a stand alone oven on the cut-off corner and a small butchers block for prepping meals with a couple of stools so DS could sit and do homework (he had just started pre-prep) alongside me.
It was a ridiculously impractical workspace although it looked naice and tbh I don't know how we coped with it for the three years we were there before selling up and buying somewhere with a larger kitchen. The new owner - who kept our dresser but put it in the conservatory - soon fitted a 'proper' kitchen, but she was an elderly lady so our set up was probably even less practical.....
In a larger space I think it would have worked better - in fact in our next house we kind of had a semi-fitted kitchen - with one run of wall and base cupboards (including plate rack and Belfast sink), range cooker in the chimney breast, mobile butchers block and 1m island unit, old repurposed sideboard and pine table as extra work surfaces/storage and a fab original built-in dresser.
This was a much larger space (two rooms knocked through) of about 25' long and it worked fine for us - although I agree about crumbs etc being an issue between free-standing pieces - but a few friends, whilst saying they loved the look, admitted they would have filled the room entirely with fitted units as the lack of a long run of worktop was impractical in their eyes. It worked for us for ten years and AFAIK two house sales and eight years on it's still like this.....
