You can (Node.js does, for example) but I don't know how
well-documented or supported it is. Googling 'icu genccode' doesn't
turn up any hits for me at any rate. :-)

ICU's source/tools/genccode/genccode.c turns the data file into a .c
file that you can compile and link into your final executable or
library. There's a bit of a chicken and egg problem in that genccode.c
itself depends on ICU but you can work around it by linking genccode
to source/stubdata/stubdata.cpp.

I'd refer you to how Node.js builds its embedded copy of ICU but it
also has extra steps to strip unneeded data and such, so it's a little
more complex than what I just described. But if you're interested, the
steps are here:
https://github.com/nodejs/node/blob/165916b1f3ec094b1694bd5a056c2fc5e56027c2/tools/icu/icu-generic.gyp

I'd like to better-understand the ECMA 402 process around small additions
like this (and your other email about "quarter"). Will this become a formal
proposal (and an attached issue, https://github.com/tc39/ecma402/issues/343)
the extent of the specification process for this feature? Is there a
"stage" process for these things?
