Unforunately they haven't bothered to highlight other engine installations in other planes which need similar flight restrictions.

This problem occurs specifically on the mentioned RR engine, due to its specific Fuel Oil Heat Exchanger design. Other jet engines on other aircraft have other designs of FOHE which have not exhibited this problem, so do not loosely assume that they also need restrictions. READ information please, when it is provided is such ample detail.
