Deploy/Push commands do not use sf cli, why?

[tehnrd]

I've noticed that deploy source to org commands appear to use the https://github.com/forcedotcom/source-deploy-retrieve library directly instead of executing commands with the underlying sf cli.

What is the reason for this?

I am trying to create a sf cli plugin, but none of the oclif hooks are running because the deploy isn't even use the cli.

web console. and perf.

same libraries underneath though. But yeah, hooks aren't supported by the IDE.
