pre-init-spec may conform data instead of just running s/valid?

[straux]

Is there a reason not to do so ? It would be useful for example for pre-processing dates or durations from config files.

After checking, it is not possible to simply replace s/valid? by s/conform: for example, it would result in a change of the data structure of the config when using s/or specs.

Instead, the application of s/conform could be set optionnal in some way ?

I think I'd rather have any pre-processing of the configuration as an explicit step.
