I don't follow. Every time I drive my car I release the parking brake. On the cars with electronic brakes, you use a button rather than a lever. I'd do it the same way to service the brakes.

A lot of electronic parking brakes do have a service mode. For most modern Fords, there is a procedure, as one example of many:

You typically need the piston fully retracted to replace pads, which very rarely happens just by disengaging the park brake.
If you are old enough to have changed a manual handbrake pad, you normally had to screw the piston back in before you could fit the thicker new pad with a "caliper rewind tool" even if the handbrake was off, the electronic parking brake service mode essentially does this for you, or unblocks the piston permitting a rewind tool to work.

FWIW, I've never found an electronic parking brake I couldn't rewind myself after a few minutes on google.
Huh. Interesting. I've never replaced the parking brake mechanism or (separate) pads myself, though I've done a handful of brake jobs.
On the cars I've worked on, the hand brake did not actuate the primary caliper so retracting the piston wasn't an issue.
