Indeed, it was for the best.
If they had used her, I doubt they would have kept her as an attractive redhead woman.
With Disney you would be extremely lucky, if they just turned her into generic girl boss with Marvel tier one-liners, and downgraded looks. That is the best case scenario, Most likely she would be a sassy black woman with red hair tint like they did with Starfire In that shitty titans tv show.
They hate Star Wars so much I doubt they would even allow her to meet Luke. If Filoni feels generous she might meet Ashoka instead. And if Luke met her, obviously she would outshine him, because she needs no man, specially not a failure like Luke ( as depicted in TLJ).
She has been spared so far because woketards think “the male gaze is le evil”. Aka anything that makes men hairy and reminds them they are ugly women IRL is bad. A blessing in disguise indeed.
