This is completely L4 agnostic though, TCP and UDP experience same rate of
packet loss due to congestion (short of specific QoS).

Obviously microbursts can (in both TCP or UDP) scenario happen without any
background traffic. Consider you're connected to 1GE port, testing another
host in 100M port, if you limit your rate to 100M, you still causes the
100M port to congest, as incoming rate is always 1GE for variable duration
(depending on how you police the sending).
