--check does not check syntax error.

for
[new section]
node.id = something

I had a - instead of _ mistake in
max.chan-ratio (instead of max.chan_ratio

Also I had spelling mistake

strategy = proportional

These were not caught during --check and instead they were caught in --dry-run

You are correct, many parts of the config file are evaluated late, after --check does its thing. --check basically only does a 'does this look like an INI style file?'

may be worth checking syntax as well as part of --check.

You are correct again, that's why I kept this bug report open :)
