As discussed in #2736.
The change wouldn't make sense to merge as is (for instance, this new
Bin_conf.global_conftype in the interface cannot be constructed from outside the module), this was more written to see how information flows. It'd need a bit of cleanup.The rpc server exe might change behavior slightly (not sure): it doesn't doesn't parse the command line at all. I think any command line flag would have been rejected by the outermost call to cmdliner anyway, but if Cmdliner terms consults environment variables, maybe something could be different here ?
Also the behavior of
update_using_cmdlineis perhaps different, not sure either. Specifically, the old code is doing something likeglobal_conf := apply_cli {!global_conf with lib_conf}vs afterlet new_value = global_conf.apply_cli { default with lib_conf }. I think this repeated mutations ofglobal_confis not necessary, but I'm not 100% sure.
