There is no negative impact involved regarding your application, as your application is already approved when the ask for the passport, I have my GCSM notes having approved status even before the date i was asked for passport and call center rep also told me the same. Only impact is if you email them then one of worker have to spend time reading the email and replying to them, which could further delay the processing as inefficient ise of time. So, if you are really need your docs early only then email them and with proof otherwise just sit and wait and consider yourself lucky as 6 month processing time for PR app is nothing compare to the previous system.
