I wouldn't say construction, but operation.  Construction is just
one packet, and payload does not immediately follow.

True, throttling individual tunnels to no more than X KBps has real
potential for some applications.  I2P 3.0 will offer this [1]

Tunnel creation itself doesn't require us to be very lucky, the
attack P = (c/n)^h is negligible.  Tunnel operation against global
passive adversaries, however, is a bitch.
