Since in 99% of cases people are either printing or viewing in sRGB, it would be interesting to know whether it makes a practical difference in day to day use to work in sRGB from the very start versus using ProPhoto/other large color space to work in and convert to sRGB at the end of PP. Besides gamut, there are also other considerations when choosing one working (editing) color space over another.

Besides gamut, there are other things to consider when choosing a working/editing space.

Unlike sRGB, ProPhoto RGB  was designed to minimize hue shifts that can occur from "common image manipulations such as tonescale modifications, color balance adjustments, sharpening, etc." (ref: Kodak's ROMM )

sRGB might not be the best color space in which to do white-balancing. Another reference here. (sRGB has the same primaries as ITU-R BT.709 compared in these references.)

I don't know if these make a big difference, but ProPhoto makes me feel better.
