>Thankfully nobody took your approach and jumped into the intake of a running turbofan engine.
You may be surprised to learn that the exhaust presents a greater danger than the intake on a running turbofan engine. You may be even more surprised to learn that there was some thought put into the emergency placards in the aircraft; the evacuation slides on modern aircraft such as the A350 are certified for use even with the engines still running, although for obvious reasons they should be shut down if possible. That is why both the fore and aft center slides are angled away from the engines.
You may be surprised to note that neither the FAA nor EASA mention running engines at all in the requirements for emergency exits and associated hardware (ETSO-C69c, 14CFR25.810).
I am not surprised at all, years ago I spent too much one-on-one time with a paper copy of 14 CFR :) There is less in those few thousand pages than most would think.
Simply because the CFRs do not require something do not make it untrue. The fact of the matter is that your original comment was simply incorrect, you would not be sucked into a turbofan engine if you use the emergency slides fore of the engines.
