Along those lines bear in mind your intentions. If you go for the fastest super high end zoom lenses the weight and size savings can be more modest. My own m43 kit includes a few 2.8 or faster primes and one 2.8 zoom as mentioned.
Example kits:
Light hiking kit; Panasonic 12-32 or Panasonic PZ 14-42 on camera. 35-100 in pocket. Using Olympus OMD-EM1 / Panasonic GX8/7/ or 1. Gives 28-200 coverage f3.5-5.6. Often my Olympus body cap 9mm fisheye comes along (fixed f8, 3 steps of manual focus) as well as the 20mm f1.7 Panasonic if I have the space. This is a light small kit. Adding the primes gives an option for low light and wide angle/ fun fisheye.
I have a Panasonic 12-35 f2.8 and use it with the Panasonic 42.5 f1.7 when I expect the extra speed is needed.
I have a Panasonic 45-175 when more reach is required.
I have an Olympus 60mm f2.8 macro when an extension tube isn’t sufficient.
I have a Sigma 30mm f2.8 when I feel the urge to use only primes (9mm f8 body cap, 20 f1.7, 30 f2.8, 42.5 f1.7, 60 f2.8 gives a range similar to 17-120 on full frame.
Bear in mind slow lenses like the 35-100 are still sharp and offer good rendering.
I also have the Olympus Air-01 I can toss in a bag as a backup camera - 16mp uses a smartphone to provide the screen needed. Or I can just add the GX1 which is tiny already.
Essentially with m43 the size limitation inwilling to carry that day is what governs my lens selection. There are excellent larger range modest sized zooms as well.
