Further follow up, 3 months and 500 clicks after the shutter replacement.
No spots have been visible in my normal shots.
I noticed 4 spots in some recent macro shots with very small effective aperture.
The blue sky + f/32 + auto-levels test revealed about 2 dozen particles. They were all hard edged and irregular shape, no oil spots like I had before the repair.
Self clean and the rocket blower got rid of some particles and moved others around. Two swipes with the Sensor Sweep brush (from Copper Hill) removed everything. Wet cleaning was not needed.
This is acceptable. There is no way to keep the sensor of an interchangeable lens camera perfectly clean, dust accumulation is to be expected. The dust that did accumulate was only visible in extreme conditions, and it was easily, quickly and safely removed.
