Distal trpR regulatory gene

Someone goes:
Why is the trpR regulatory gene distal while lac operon's LacI gene proximal to the promoter? What is the purpose? Isn't it better to have the regulatory gene close to the operator for quick access and a better response to environmental changes?

Yea. However in the case of the trp repressor, the protein has been found to be capable of binding to at least 5 other operators in other operons as well. Thus its distal nature in trp operon could have been a compromise.

Cheers
