Oh wow. That's a deal-breaker to me, because X3 is experimental AND has significant issues.
Some things are hard/impossible to port from Qi to X3 - exacerbated by the (spurious?) decision of a dev to not only "not implement" a qi::lazy pendant, but even go so far as to deprecate the essential building block `x3::any_parser` - which is like a type-erased x3::rule (https://github.com/boostorg/spirit/issues/530#issuecomment-3254447450)
If the problem is that that Qi is not maintained, THAT should be fixed, as it is by far the most mature component in the Spirit library.

Seth, you're the best person I can think of for maintaining the Qi codebase, if you are willing to do it. Regards, -- Joel de Guzman Cycfi Research, Inc.
