I think this is because in SAS by default we get detailed log.. listing out each and every step with ERROR/WARNINGs or NOTES, this is quite helpful in debugging.
On top of it you also have debugging options like - MACROGEN SYMBOLGEN MLOGIC MPRINT MFILE, which allows you to dig deeper and get even more detailed logs.
Looking at SAS log only you can make out what exactly the code is doing... you get the whole story documented itself - how many observations where read from input dataset and how many variables the new dataset have and if a variable was left uninitialised or truncated and lot more.
Its so well documented that you can retrieve your SAS code from its log using a simple regular expression.
However, I struggled to get SAS like logs in R & Python.
