Verify partial_chain with custom ssl_options

[spydon]

If I'm not mistaken it is not possible to use the default partial_chain option when using custom ssl_options in 1.16.0 since partial_chain/1 isn't exported anymore.
Or is there a possibility to merge custom ssl options with the default ones?

check_hostname_opts/1is exported from hackney_ssl. Depending on what you need that maybe enough. I can provbably export the partial_chain callback if needed. What require your custom ssl options for now?

Thanks for the quick reply!
I think we mainly use a specific verify_fun and also swap cacerts to cacertfile in some cases.
The most useful would be if there was a way to use the hackney SSL defaults opts and then just override a few instead of all of them, is that possible somehow?
