Understood. Many applicants never do or even request their GCMS file. It has no adverse impact and it's your call. About the 6 month mark, here is some info about it.
In 2019, IRCC did not meet the processing standard of finalizing 80% of all applications sourced via Express Entry within
six months. The processing time for Express Entry, overall, was
eight months. As an alternative measure of processing times, 60% of applications finalized in the 12-month period ending on December 31, 2019, were completed within the six-month service standard.
