Hi, I like your reasoning and think it is makes a lot of sense.
If I was to play devil's advocate, these would be the observations:
The relevant guiding documents here are OM-B*, and AFM. We are expected to operate within the prescrbed limits, even when FCOM, ECAM or else do not warn us (yet).
AFM clearly states FUEL TEMPERATURE LIMIT maximum +54 deg C. If the fuel temperature indication is correct** and above this limit, the aircraft is beyond certified state.
cheers,
FD.
* FCOM is a legal part of OM-B here, a common setup I suppose;
** I had experienced HI TEMP indication while no. 1 at holding point of a very busy international airport. With all the bells and whistles you describe Tiennetti, including a very straightforward ECAM action line to shut down the engine. Here's what I found in FCOM later on, hidden to me until later that day:
This caution may spuriously trigger due to interference from communication equipment. Therefore, the flight crew should wait 2 min while the fuel temperature measurement is updated. After 2 min, if the ECAM caution has not disappeared, the flight crew must apply the following procedure:
