The option is already in the .bashrc (though commented) of my version.
Neat. Might be the default aswell.

$ info bash HISTCONTROL

If history is enabled by set -o history, the default action if HISTCONTROL is
unset or null, saves all instances of all commands, except those excluded by
patterns in the HISTIGNORE list, up to the limit specified by HISTSIZE, default
500.

To get the result you probably expect set "HISTCONTROL=ignoreboth:erasedups"

'info bash HISTCONTROL'

It sounds like you are asking for the Cygwin /etc/profile (or the
skeleton .bashrc file) to be tweaked to add a HISTCONTROL=ignoredups so
that new installations automatically turn on that feature of bash.  But
in the meantime, you can modify your own ~/.bashrc to turn it on for
yourself.

go through duplicate commands

[A GS]

What about making "up" go through duplicate commands? I think this is the behaviour on some linuxes but I don't know the specifics. That would be neat.

ls -a
ls
ls

This would go from ls to ls -a in one (not two) "up"s.
