From a Lore perspective it actually makes a ton of sense - to me. And would be on brand.
Wilders do all channeling based on need. They would not see the OP the same way as those trained within the rigid constraints as Aes Sedai. There are ups and downs to this though. It would allow for more flexibility and "inventing" but also would not allow for as much finesse.
Take for example Lan and Rand early on. Both had killed a trolloc using a sword. Rand out of the need to survive - and Lan because he's just a certified badass. Nobody would argue that luck didn't play a HUGE role on Rands early survival ... maybe the Creators hand tipping the scale a bit. But still they were both officially "swordsmen" in that they had done battle, drawn blood, and survived.
Lan would have absolutely wiped the floor with Rand.
-------------------
Also Aes Sedai who are already locked into the mentality that - there is a specific weave...with specific motions and specific amounts of power drawn from threads would immediately blame - lack of training. Because in there eyes if they haven't seen, learned, and practiced a weave - how could they do something?
Its that rigid mentality that likely caused much to be lost in the breaking, and why we "rediscovered" weaves later.
That said there are ups and downs. A Wilders shield likely wouldn't be up to snuff against a full trained AS who put in the hours. I'd take Cadsuane shielding me over a billion wilders.
