How would one handling starting a new projection from the offsets, hold back the consumer until the response comes back from this API, because it would start consuming from start as soon as it has started executing, right?

Just an idea so far...
For the Durable State change events it's possible that you start out with ordinary Durable State and then enable change events later. Meaning that there will missing events and offsets for earlier sequence numbers (revisions). The offset validation will reject them and the projection will be stuck.
One way would be to populate the offset store with known "starting points" via the projection management api.
In general, we are lacking projection management for timestamp offsets, because they are not a single value.
