Wasn't the problem somewhat different? There have always been "fast-math" version of some costly function. So, the point was, whether the faster routines could be used at the price of their larger numerical errors. Similarly, the choice of the optimization level of a compiler needed to be checked. Furthermore, the wide spread use of fortran for numerical intense simulation up to this date stands in contrast to your statement, in particular in the field called high performance computing.
