data.table is doing the same in a number of places, Ivan even went so far
as to pin down a specific SVN commit for those as well:
#if R_VERSION < R_Version(4, 5, 0) || R_SVN_REVISION < 86702
# define isDataFrame(x) isFrame(x) // #6180
#endif

FWIW Rcpp handles this (for CLOENV) with an ifdef:
#if (defined(R_VERSION) && R_VERSION >= R_Version(4,5,0))
return R_ClosureEnv(fun);
#else
return CLOENV(fun);
#endif
