To B or not to B

The B setting on cameras, you'd have thought that in this day and age the B setting could be a toggle function as the only reason to use B is typicall for exposures of longer duration than 15 or 30 seconds which appear a common maximium.

So B for long exposures of 30 so how can I hold this shutter release down for say up to an hour or perhaps longer...

Why can't the B setting be updated to a toggle function..via firmware..or a new function added, other than wanting to sell expensive remotes.......
I can trigger my EOS M3 with my ipad but why can't I have longer exposures via the ipad it'd be relatively simple to program I'd have thought.
Just keep sending the open instruction to the camera for an amount of time set on the ipad.

NOSPAM what'd ya reckon up for it, although canon might have sopmething to say about it.





It used to exist, in the age of mechanical in-the-lens shutters, it was
called the T setting (for time). If you pressed the cable release, the
shutter would open, another press and it would close. Like electrical
cars, it might seem a new idea, but in fact it's very old. Few people
know that before the advent of gas engines people used to drive electric
cars, with lead batteries goes without saying as it was the only battery
chemistry available back then. And for the same reasons people think
electric cars are better now (clean, no emissions, no noiseetc.) Only
thw writing on the wall appeared for electric cars with the invention of
the electric starter. After that it was a no-brainer for gas cars.
