Something similar happened in the past: Scandinavian Air 751 (MD-81 with twin engine aft-mounted) had both engine surged due to ice ingestion shortly after takeoff. Pilots were not aware of auto throttle control, which revert pilots’ action of reducing throttle (to fix the engine surging). Both engines ultimately failed and aircraft crash landed. Luckily all survived.

Well, the throttle control was one issue, but it is far from certain that it would have saved the engines. The main issue was still the ice that went in to the engines to begin with. The full report is available here:

I agree. Improper de-icing + aft-mounted engine is the main cause of this disaster (although ice on wing itself is already a problem as it reduces lift and could cause stalls). My (rather subtle) point is that Boeing can’t really go “oh this has never happened before”.

In fact, as a general rule of thumb, I believe any safety feature that would automatically change the state of the aircraft should be well educated to the pilots.

I understand how the term 'ingestion' got to be used but given how turbines react to foreign objects, 'indigestion' seems more accurate.

You have to ingest something to get indigestion, resulting in sentences like "ice ingestion gave the turbines indigestion". At that point it's long-winded and would be shortened to "ice ingestion", making the point somewhat moot.
