The all-carbon mini-pumps are intended as pocket-minimalist, so probably half of the volume per stroke as this one. It would be interesting to compare them in actual use on same-sized tires.
What the super-light carbon pumps also lack is the grip size, so pumping is of course less comfortable.
I have to say that my ten-years-newer Shimano Pro Carbon pump is higher-performing than my (also 39g) old SKS SUB40, no surprise there, but the quality of the internal seals seems quite well thought out on both of them.
In this age of disc brakes and fatter tires, weight-weenie-ism is perhaps taking a back seat to other comfort and performance criteria, so pump marketing might be following that same course.
This thread had me getting up to weigh a 12g CO2 cartridge, which at 45g with a ~10g inflator valve seems like another minimalist approach (or as a back-up to the micro-pump approach). Both fit easily in a jersey pocket [for those not fearful of being possibly(?) impaled in a crash].
