I never even found it a mild annoyance to access, empty and bleed the MC. I use a plastic (LDPE) disposable pipette to empty the reservoir first and wipe it out with a paper tower if there is any residue - this reduces the amount of fluid you have to pump through the system since you are starting with all fresh in the reservoir (same with clutch and front brakes). These are between 2 and 3 millilitres per squirt.

A little fussier if you are removing the rear brake pivot to clean/lube - cotter pin and springs were a bit of a puzzle the first time.
It is still easier than replacing the air filter on the other side.
