A 22T chainring on a 34T rear cog is pretty damn low. I'd be happy with that. A triple chainring on 7-8 speed is pretty flexible.

As for 'new', I've gone for a Pinion 30T/30T on a Sturmey Archer CS-RK3 3 speed IGH, which basically means a linear range of 18 speeds in normal terrain, with 'overdrive' for descents over 40km/h, and a 4x4 style low range 'granny' gear for ascents over 8%.
