I have to agree with this.
Despite all the hoopla about web standards, ultimately the truth is that Flash (Adobe Animate) is still the leading tool for making modern animation. Most modern TV shows are being produced with Flash, and its still being pushed at universities as the tool of choice for content. The other tools such as harmony and even Moho know this and make every effort to remain compatible with the technology. After all were not making web banners and games etc... were making movies.
Of course by bringing back SWF export you would be empowering all animators with tools they just dont have.
Flash bone tool is a joke. But CTAs G2 system is ground braking. I bet if this were brought back, most animators would not think twice about using CTA for their base character animation tasks, knowing that they can export their animated objects back into Flash for more advanced stuff.
