And 7spd is 5mm with 8spd 4.8mm - what's 0.2mm between friends?

1.2mm across the block, you don't count the first cog, only 6 shifts. Thumbies work fine because once you've used the float you also have the inaccurate indexing that help out.
How do ratchet, RF/RF+ based indexing fair, I never did try. Still just run an 8 SPD shifter, the stops will lock it out.
12 - 28 XTR M900 (Q? type) take out the 13 tooth cog and voila a 7 speed lightweight 12 - 28 cassette with usavel ratios. Admittedly only if your using non compact rings (same for an M950 11 - 30 remove the 11t and you ahve the older 13 - 30 "G" 7 speed cassette ratios.
getting an 11 - 28 XT M737 and removing the 28 would be neigh on impossible as the 24 & 28 T share the same alloy tab they are pinned into. (so it would be remove the 11t cog as per xtr)
after that its SRP Tioga and Goltec TI cassettes or mix and match SRAM as suggested.
