Could jmh respect system format settings on Windows or use "C" (simplest one) for machine-related output (CSV)?

 I use Windows with Russian regional settings with CUSTOM decimal
delimiter (set to ".", dot, of course).

 JMH 1.13 outputs numbers into CSV with comma! It is complete madness!
No software (Excel, OpenOffice Calc, Google Docs Sheet, gnuplot) can
import/use such CSV on my system! I need to change it with regexps every
time I want to import it!

 Could JMH use not "regional" but "neutral" locale for machine-readable
output? IMHO, using regional settings for machine-readable formats is
pure evil (and thanks god, that JMH doesn't generate PostScript with
same approach, for example).
