It's OK as-is, as the "Mongol" ruleset's last rule is:

Rule    Mongol    2015    2016    -    Sep    lastSat    0:00 0    -

so that standard time is in effect for the indefinite future. True, we 
could complicate the Zone by adding another line that says just "+08", 
but the usual style is to keep the zone lines simple.

You can verify that Asia/Ulaanbaatar is OK by looking at its entry in 
to2050.tzs, a file delivered as part of the tzdb-2017c.tar.lz tarball.
