Lemme be the one to say the truth: The LCS does it so now people are doing it.
Is it smart?
-
No, because most bot laners playing this game don't have the macro sense to use teleport for roams properly.
-
No, because the enemy will have heal/ignite and that means you've just lost lane for no reason. Congratulations.

No, because even if we wanted to spearhead the idea and force it to work, anyway, people are banning out Yuumi so you can't even weasel your way out of the weakness described by the second point.
The result is, unless your jungler loves the way you smell and the way you walk down the street enough to dedicate his time and calories on you, you lose lane and pretend you're a big brain player by teleporting back to the slaughterhouse, where you'll die again. The only time I've won with a tp lane partner this season is when I was Yuumi...which happened once total. That spell's cd is huge and it's a poor choice in a lane where people are stacking heal/ignite in an environment where people play way more aggressive when junglers AREN'T around than pros do.
