From a macro point of view, it seems wasteful to have so many brands and sensor size formats.
Not too environmentally friendly.
Over time and slowly, consolidation occurs and the disparate product genres, brands and product model lines are reduced to a few.
One wonders what happened to the unsold stocks of all those cameras and lenses of dead brands .
Probably not cost effective to disassemble and recover the materials.
So they may have ended up buried in land fills.
Thus the death of an unpopular and obsolete digital sensor size format may eventually be good for the environment.
Less wastage.
The counter point is that consolidation leads to oligopoly by a few dominant brands.
