Bevy is still in its very early days. Using their limited development time to develop for what is already today old hardware doesn't make much sense considering its peak is likely another 5+ years in the future. By the time Bevy is very mature, the hardware that is only able to run OpenGL will be even less relevant and a very small niche.
That being said, as far as I know Bevy is modular enough to write third party render backends. If it keeps growing, I'm sure someone will do that.
