Refueling satellites will absolutely be a thing :) Restore-L is going to do just that in 2020-2021, and do it autonomously to boot.

I work on Restore-L and believe me, there is a huge need for on-orbit satellite refueling and reservicing. The vast majority of satellites reach their end of life due to depletion of fuel, not due to electrical problems or sensor issues. This will be a huge business one day.

But will sats be refueled or will they simply have new service modules attached to them, bypassing all the tricky plumbing issues?

They will be refueled.
