There's the problem. The reason the thing you're replacing is so complicated is because it tries to codify some aspect of human behaviour. If your solution for handling (e.g. money) is radically different to the existing (financial) system (which this is), it will probably blow up in a big way.

In practice I think it's likely that most law firms and jurisdictions who configure and accept business ownership structures enforce their terms in a nearly-as-restrictive manner. No doubt there are exceptions; a file format can be adjusted over time to handle those equally.

The file format should -- and to some extent, is already -- separated from the mechanism(s) of payment.

Version-controlled software development is social and provides history, evidence, and allows code to evolve over time; I like that this approach leverages those properties.
