Kind of annoying especially when you're tryna place a bunch of spawners at once. Doesn't particularly take up a bunch of time. About as annoying as a YouTube ad. It's pointless to have it unless there is some unknown reason (whether it be lag, glitchy, etc...) that the general public of players doesn't know about.
I support a lower cooldown, but feel it's needed to stop people changing the spawner type every other second
