Engineers still have to calculate exergy and the availability of energy when steam is supplied to a power plant or geothermal energy is used to produce electricity. The statistical definition of entropy may be more modern and may be more definitive, but it is not easy to use in many engineering applications.

This is IMHO a sufficient reason for not bothering with classical
thermodynamics, and sticking with a modern (post-1898) definition
of entropy, i.e. the /statistical/ definition.
The 1800s have been over for a while now. Classical thermodynamics
has been obsolete for more than 100 years.
