Wow, I remember this recurring extra-modeling-schemes conversation about Blender, and other FOSS mesh modelers from at least 2003...? Lol.
(In 2D land, Inkscape actually retains a few of these various convenient add-on vector drawing methods to this day)
The 3D modeling pitches were also always supported by CAD folks, who were looking to sideload about 10 tons of CAD kernel onto the latest parametric undertaking. Like, give us infinite modeling accuracy and resolution or give us death!
One issue here is this scrappy, Blender-style "whatever works in the final cut" Hollywood mindset [1] vs. the "can I recommend this, as a platform, to all of my friends" mindset in which all contingency needs must be covered, and so Blender is never, ever good enough for you, maybe. Or perhaps the "model itself must be exported directly to high-accuracy industrial plans" mindset.
The former is easier on FOSS teams. The latter always invites this "fork it" mentality and you sometimes get these temporary Frankensteinian spinoffs called "AutoBlenderCAD 3D", etc.
Also reminds me of JPatch? And some other third-party FOSS projects, RIP...
And: Cool if it turns into something great, even if for a while!
