1. "IPA client can send metadata fingerprint with request."
When the client will send the metadata and when it won't? It will for
all 4.4+ servers? And won't for the legacy ones?

2. How the client will determine #1? Will it use ipa ping in the very
first request and then use this version of metadata until version(legacy
server) or metadata fingerprint changes? Which will trigger download of
metadata in next request?

3. I don't much understand:
"""
To avoid breaking users' scripts the client MUST use the oldest version
of command available by default. User CAN change the default behavior to
use the latest available version instead of the oldest and CAN specify
per command override.
"""
What is the oldest command available? E.g. I have a 4.4 server and 4.5
client. Is it 4.4 or some older, legacy one? If I have 4.5 server and
4.4 client is it 4.4 with available override to use 4.5 given that the
client knows new version of command from metadata?
