Bugzilla [1] seems to be the best place but here it is equally good.
After all, your voice is being heard.

Correct.

Thank you for spotting a reporting the problem.

Indeed, ru_RU provides two-letter abbreviations as you quoted
while CLDR [2] provides the same but says they should start with
lowercase letters.  But the lowercase/uppercase issue is always
controversial in the languages where names of weekdays and months
do not start with an uppercase letter by default and no solution
is perfect so I assume that it's better to leave it uppercase,
as it is now.

When you said "copy days of the week from ru_RU" probably you meant
literally copy and paste, but given that there are almost no differences
in LC_TIME between ru_RU and ru_UA we can also use “copy "ru_RU"”
in LC_TIME in ru_UA.  Please note that it is impossible to copy part
of the section and impossible to modify it, either copy whole section
as it is or keep two separate copies.

There is only one other difference between ru_RU and ru_UK:
in ru_RU ab_alt_mon (abbreviated month names in nominative case)
begin with a lowercase letter while in ru_UK they begin with an
uppercase.  Is it OK to unify them?  Uppercase looks better for me
in this case, OK to make it uppercase, that is copy ab_alt_mon
from ru_UK to ru_RU?

If you are curious where to see ab_alt_mon in real applications
the answer is: in calendar headers (if they are abbreviated).
Never in full date formats.
