One very practical method is to do fillets at the end and before you make the fillets save off a version of your model to a separate file. Then if you want to redo the fillets load in your version you saved before applying them and make new ones.

Feature recognition and defeaturing are very complex processes that would require many years of geometry algorithm development work, it's a long ways outside of the scope of what can be done with a script.
