I'll fork it in about 30 seconds.
And neither of us will get any traction, because the QGIS team has a history and proven track record within the GIS community, and neither of us are attempting to solve a problem that community has.
Couldn't happen sooner.
The majority of LLM use is to make slop or answer simple questions that could have been searched. The mythical AI-Chad Coders are so rare that catching them in the anti-slop dragnet will not meaningfully decrease the quality of a big project.
The question is whether or not you are willing to support your creation for the next two decades.
Second, majority of apps do not last 2 decades.. and that is okay... someone else can fork the repo and continue if needed.
If not you may want to familiarize yourself:
What a track record!
Most of the GIS people I know, and I really know some, are totally oblivious about the underlying magic of QGIS or ArcPRO, and many of them would happily go away from both for many reasons.
Mind U - ArcPRO is also an ecosystem, no only maps layer, is actually an ERP of sorts, when tied with the ArcServer and the rest in their design. But is quite heavy, super bloated (ArcPRO brings own Python, Postgres, Java, and perhaps the whole proj+geos libs also and whatnot).
