Agree that forcing the standards on people is a bad idea.
My implementation would be to not enforce anything unless the developer decides to use the standard after which the code should be reviewed for the standard compilance
As discussed above the concern is trust and robustness of the project so that it can be used as superior alternative by governments and businesses that require the software to be designed for mission critical environment.
I don’t want to enforce coding style as long as there is CI implemented that formats the code e.g. GNU Indent.
I guess this could be phrased as “coding recommendations” to make it a subject to the current standard maintainers instead.
