I agree that we need to allow the configuration of older TLS versions in
the YANG module.

I found this comment from Ben to be useful -
https://mailarchive.ietf.org/arch/msg/last-call/oVO7XyHyTtX4bdkpN9PymiovieA/
. I ended up putting MD5 and SHA-1 support under a feature 'deprecated'. In
this case, I think just adding some text in the description around the
existing features for older TLS could also do the job.

Thanks for taking my comments into consideration!
