No support. If the timer was bypassed, essentially the mod would bypass anything with a timer. This would be extremely easy for a mod to accidentally abuse. Scenario 1: WITH A TIMER Mod is PvPing, dying and runs away. They run into a corner, panicking and /spawn, as the timer is going the player just gets to them at the last second and hits them. /spawn failed. Scenario 2: WITHOUT A TIMER Mod is PvPing, dying and runs away. They run into a corner, panicking and /spawn. They are taken to spawn with no timer, essentially giving the mod an advantage over the players. Also, it's only five seconds. I've personally never had a player complain that I've taken to long to TP in all my times of TPing.
