The non-ATM bus stops around where i work have still the blue bus stop signs like that.
But this one, at Sesto Marelli M1 only has the timetable stuck to the shelter and no sign at all

They do indeed exist

Although that section is still somewhat operational, mainly to bring line 2 trams to/from Messina depot since there is no curve at the intersection of Farini/Ferrari (from what i can see from the timetable, only the curve towards Bausan/Niguarda is regularly used)
(Also, the images show Via Ceresio)

A bit like the line 15 extension deeper into Rozzano in Milan

Oh sorry, I mean, EDSA "bus carousel"

I guess the EDSA busway in Manila could also count? It's rather weird

Interestingly, recently Regione Piemonte and Arenaways have come together to make a Malpensa-Novara service, using a curve only used in 2006 and in the past deemed unstainable due to high costs by Trenord

Milan:
"Urban" lines (using that term lightly): all doors boarding (like the rest of Italy (mostly)
Interurban lines: Front door boarding, rear door de-boarding
