Petition to make changes on damage redirection

Petition to change the condition "basic attacks" to "physical damage".
I think we should allow damage redirection apply to ALL physical damage instead of just basic attacks.
For one thing, it makes sense thematically, considering most physical damage abilities utilize the champion's weapon there's no thematic difference between these abilities and basic attacks. Here's a few examples of abilities that don't apply "thorns" despite being a form of attack:
Garen's E causes him to spin around and damage enemies with his sword. His sword hits- that should proc "thorns".
Pretty much Kayn's entire kit uses his weapon to strike the target, but abilities do not proc "thorns".
Same as Kayn- and even more important due to his Passive. Darius stacks from his abilities are the same essential problem against Thornmail that caused Thornmail to be reworked. Except instead of Lifesteal you just bleed all over the place when he slams 5 stacks in 2 seconds.
Another key reason "thorns" should apply to all physical damage is the utility. Champions with physical damage abilities can simply abuse abilities to gain their Attack Damage bonuses without the pain of "thorns". A great example of this abuse would be a Rammus W versus Garen E. Rammus W is weakened by Garen's E, and without any consequence to Garen. I understand Garen has his own issues- but that's not what I'm here to talk about. I also understand, as a Rammus main, that Garen should counter Rammus- again that's not the point I'm trying to make. Garen's E does such little physical damage that the small amount of damage he would take from "thorns" is negligible- but it would give him some consequence to use such a hard Armor counter. Thornmail is rendered to shreds with the combination of TBC and Garen's E- let it stay that way- but also allow the Thornmail to punish ALL physical damage and we got some counter-ability.
